The pentose phosphate cycle has an oxidative and a nonoxidative section and these are presented as both playing important metabolic roles, rather than a coupled role with a single function. How are the metabolic roles of these two parts of the pathway different from each other? Explain in terms of biochemistry Solution Answer= Function of oxidative and non-oxidative phases of pentose phosphate pathway Oxidative phase= produces NADPH = it serves as a source of electrons for the reduction of molecules during biosynthesis Nonoxidative phase=1] synthesizes 3 & 4 carbon sugars for various purposes 2] The 4 carbon sugar erythrose 4 phosphate is used to synthesize aromatic amino acids & vitamin B6 3] The pentose ribose 5-phosphate is a major component of nucleic acids, and ribulose 1,5- bisphosphate is the primary CO2 acceptor in photosynthesis. 4] Intermediates in the pentose phosphate pathway may be used to produce ATP. 5] Glyceraldehyde 3-phosphate from the pathway can enter three-carbon stage of the glycolytic pathway and be converted to ATP and pyruvate..

Standpoint theory suggests that our understanding of gender-based communications acts is shaped by our standpoint in life. How does a persons standpoint as a member of one sex (male or female) shape your experiances and interactions with other? Explain how other standpoints, besides sex and gender, help you to understand your position or location within our culture. Solution Standpoint theory\'s most predominant abstraction is that an independent \'s own prospect are shaped byher or his political and social experiences. Standpoints are multifaceted rather than transitive: while Hispanic women may predominantly share some prospect, particularly with consider to ethnicity or sex, they are not explain simply by their involvement in these group.

Parthenogenesis has been documented in most vertebrate Classes (e.g. birds, fish) but never in mammals. Genomic imprinting provides one explanation for this observation. Why? Solution Parthrnogenesis is the process of reproduction from ovum without fertilization. It has been documented in most vertebrates but never in mammals because of polyploidy and hybridisation. On the cellular level, the distinction between parthenogens and sexuals is that, meiosis is accompanied by fusion of a male and female gamete. In parthenogenesis, meiosis is changed so that only one unique set of chromosomes is transferred in a non-random fashion. Germ cell doesn’t have centrioles (they’re lost throughout gametogenesis), the lack of centrioles is not a restrict to the egg cellular. The genomic imprinting, i.e. that sure genes will no longer activate unless paternal genes are lacking. That is an trouble with mammals and no longer with the parthenogenic vertebrates because mammals have an overabundance of a protein referred to as mos. when absent, automixis occurs (it normally blocks cleavage formation inside the oocyte, therefore, the oocyte can’t undergo automixis)..

Home Savings Association, Respondent, Upper Northwest Payment Plans Co., Respondent No. C6-87-1497 Court of Appeals of Minnesota 416 N.W.2d 786; 1987 Minn. App. LEXIS 5110; 6 U.C.C. Rep. Serv. 2d (Callaghan) 35 December 3, 1987, Decided December 15, 1987, Filed PRIOR HISTORY: [**1] Appeal from Hennepin County, District Court, Hon. Ann Montgomery, Judge. DISPOSITION: Affirmed. CASE SUMMARY: PROCEDURAL POSTURE: Appellant homeowners sought review of the decision from the Hennepin County, District Court (Minnesota), which granted summary judgment in favor of respondents, savings association and payment plan, on the homeowners\' claim of tortious interference with contract. OVERVIEW: The homeowners entered into a conditional sales contract to purchase a mobile home. Subsequently the contract was assigned to the savings associationThe homeowners argued that thetrial court erred in determining, as a matter of law, that their claims of wrongful interference with contracts were invalid. The court determined that the trial court had correctly determined that a contract between the homeowners and a subsequent buyer could not arise absent performance of a condition precedent, which was the approval of the subsequent buyer\'s assumption of the loan. Even if this court were to determine that valid contracts existed between the homeowners and prospective buyers, the issue of justification would have to be addressed and the savings association and payment plan would have prevailed. Credit checks and equity interests were commercially reasonable assurances and could not be met by the prospective buyers. The savings association and payment plan were within their right to refuse the assignment. OUTCOME: The court affirmed the decision from the trial court. CORE TERMS: mobile home, materially, prospective buyer, breach of contract, assignee, buyer\'s, purchase agreement, assignor, summary judgment, down payment, substantial interest, conditional, assurances, assigned, inducing, delegate, condition precedent, contractual, contingent, delegation, tortious interference, credit check, right to refuse, wrongful interference, contractual duties, equity interest, delegating, purchaser, happening, default LexisNexis(R) Headnotes 1 of 7 4/4/12 5:11 PM http://www.lexisnexis.com/lnacui2api/delivery/PrintDoc.do?jo...

Listed below are the major steps in protein synthesis and some events that do not occur during protein synthesis. From the list select those events that do occur in protein synthesis and place the letters of these steps in the correct chronological order. A) DNA attaches to ribosomes B) Amino acids bond to mRNA C) mRNA processed (introns removed) D) amino acids carried by tRNA joined together E) mRNA leaves nucleus F) DNA replicates itself G) mRNA replicates itself H) mRNA attaches to ribosomes I) mRNA produced using DNA as template J) tRNA and mRNA become part of finished protein K) tRNA anticodons bond to mRNA codons Solution Translation is the process where synthesis of appropriate amino acid and polypeptide chain takes place taking mRNA synthesized from the target DNA sequence as a reference. Translation takes place in the cytoplasm over the ribosomes of rough endoplasmic reticulum by a comprehensive action of mRNA, tRNA and other accessory ingredients by utilization of energy in the form of ATP. The sequential process of translation can be found as below: F) DNA replicates itself I) mRNA produced using DNA as template G) mRNA replicates itself E) mRNA leaves nucleus C) mRNA processed (introns removed) H) mRNA attaches to ribosomes D) amino acids carried by tRNA joined together K) tRNA anticodons bond to mRNA codons B) Amino acids bond to mRNA From the sequence above, it can be seen that the point A, i.e. DNA binds to ribosomes, is not included. This is because DNA does not bind directly to the ribosomes during any part of translation. Conversly, DNA is transcribed into mRNA which is translated into amino acid polypeptide on the ribosomes. Also, the point J) tRNA and mRNA become part of finished protein, is not included because tRNA and mRNA are never the part of finished protein. The protein is translated from the mRNA sequence by utilizing tRNA function..

1.What are 2nd messengers? Give specific examples. How are they used un signal transduction? 2.Signal transduction by RTK signaling pathways 3.Explainhow RTK are activated and inactivated 4.Explainhow signaling pathway mutants are used to dissect the functions of signaling molecul Solution 1). Receptors are the protienious structures that act as “signal transducing molecules.” There are three kinds of membrane receptors namely, ligand gated receptors, G-protein coupled receptors and kinase linked receptors. Primary messengers receive the stimulus information from the external environment and passes into the cell. If the primary messenger cannot pass through the cell membrane, receptors use second messenger for communication between the receptor and intracellular environment. Secondary messengers relay the signal information from the receptor-ligand complex, to the interior of the cell. G-protein coupled receptors are also known as heptahelical (seven transmembrane-spanning) receptors. They are connected to the intracellular system through G-protein molecules that activate secondary messengers. The three important secondary messengers are cAMP (cyclic adenosine monophosphate), IP3 (ionositol 1,4,5-triphosphate), and DAG (diacyl glycerol). Adenylate cyclase is an enzyme that converts ATP (adenosine tri phosphate) into cAMP. cAMP is one of the important secondary messengers of G-protein receptors. Phopholipase C is an enzyme that hydrolyses phosphatidylinositol bisphosphate (PIP2) into two second messengers namely, ionositol 1,4,5-triphosphate (IP3) and diacylglycerol (DAG). Adenylate cyclase is an enzyme that converts ATP (adenosine tri phosphate) into cAMP. cAMP is one of the important secondary messengers of G-protein receptors. Phospholipase C is an enzyme that hydrolyzes phosphatidylinositol bisphosphate (PIP2) into two-second messengers namely, inositol 1,4,5-triphosphate (IP3) and diacylglycerol (DAG). IP3 increases the calcium release from endoplasmic reticulum by acting through IP3 receptors. DAG diffuses through the plasma membrane and activates protein kinase C. PKC is present in many isoforms, which is activated by raised intracellular calcium levels . Calcium activates calmodulin protein by allosteric binding and thus activates calcium- calmodulin dependent kinases. The calcium-calmodulin complex activates the myosin light chain kinases by phosphorylation, which causes muscle contraction. In contrast, the cAMP acts through Gs type of GPCRs, IP3 acts through Gq type of GPCRs. The secondary effector in cAMP pathway is PKA (protein kinase A), the secondary effector in IP3 and Calcium-mediated pathways is PKC and calmodulin (calcium directly acts on calmodulin)..

(name every complete allelic copy) (2, either PP or pp) I have included the answers in the parenthesis after the question. Please explain how to get the answers in details please :) Solution The organism is Pp. It will enter Meiosis I after completion of interphase. So, the genome will be ‘4n’, when entering Meiosis I, i.e. “PPpp”. Crossing over will result in formation of “PpPp”. But there is no crossing- over in Prophase I. So, “PPpp” will go into metaphase I and subsequently into Anaphase I. At anaphase I, \'PP\' will go towards one end and \'pp\' will go towards another end. So, genotypes of the two dsDNA molecules should be either \'PP\' or \'pp\'. Both will be homozygous..

Explain why a gallstone located in the bile duct at a point distal to the entry of the pancreatic duct might result in elevations of serum amylase and serum lipase (perhaps as high as three times the normal values) and abdominal pain. Neuroendocrine tumors (NETs), also known as “islet cell tumors” are relatively rare cancers for which the majority (85%) function to produce hormones. NETs include Insulinomas, Gastrinomas, and Glucagonomas. In fact Zollinger-Ellison Syndrome (ZES) is the cause of a form of peptic ulcer disease (PUD) resulting from neoplastic duodenal or pancreatic G cells. Describe how a gastrinoma causing ZES might cause PUD and discuss the extent to which H2-receptor antagonists or proton pump inhibitors would be effective in reducing the symptoms associated with ZES. Solution Ques-1: Explain why a gallstone located in the bile duct at a point distal to the entry of the pancreatic duct might result in elevations of serum amylase and serum lipase (perhaps as high as three times the normal values) and abdominal pain. Answer: The bile duct is a vessel, which drains the bile juices into the digestive tract. These bile juices help in emulsifying fats and enhance their breakdown in body. A gallstone located in the bile duct at a point distal to the entry of the pancreatic duct might result in elevations of serum amylase and serum lipase because acute pancreatitis in which \"lower acinar cell mass\" may be observed along with macroamylasemia and under severe conditions, it leads to Jaundice (due to block of pancreatic duct) Ques-2: Neuroendocrine tumors also referred as islet cell tumors are relatively rare cancers for which the majority (85%) functions to produce hormones. These tumors are also a precursor for generation of Zollinger-Ellison syndrome or peptic ulcer disease. The major gastrinoma causing zollinger- ellison syndrome is due to chronic carcinoma developed from peptic ulcer. This peptic ulcer formation is due to either stress or due to Helicobacterium pylori. Gastrinoma is mainly associated with gastric parietal cell apoptosis and leading to caspase mediated gastric cell necrosis & apoptosis through extrinsic and intrinsic apoptotic mechanisms. This apoptosis is leading to gastrinoma with peptic ulcer disease due to severe acid secretion through histamine- mediated activity. This is also due to the following infection inside gastric area. Bacteria, Helicobacterium pylori produces, catalase, urease positive tests and showing up biofilm formation on gastric mucosal layers with several colonies (coccoid forms) on his stomach biopsy slides. It can be visualized using scanning electron microscopy & confocal microscopy. These are flagellated & phospholipids and lipopolysaccharide. Helicobacterium pylori feeds on mucosal cells finally due to the rupture of mucosal layer, the gastric juices secreted directly attack the abdominal wall. This causes severe pain in the mid of the abdomen or upper abdominal region. Proton pump inhib.

Family members with eye cataract are shown with a solid left half of the symbol; those with pituitary dwarfism are indicated by a solid right half. Individual IV-1 and IV-5 decide to have a child together. What is the probability of their first child having both eye cataracts and dwarfism? Solution If I-1 (mother) is the carrier for eye cataract and 1-2 (father) is a carrier for pituitary dwarfism, we can see that the first child is unaffected (II-1). Same case we can also find in III-5 (carrier for eye cataract) and III-6 (carrier for pituitary dwarfism) are married, their first child will be uneffected (IV-4). Ans: In the same way if IV-1 (carrier for pituitary dwarfism) marries IV-5 (carrier for eye cataract), the probability of their first child having both eye cataract and pituitary dwarfism will be Zero. Note: Probability is defined as the extent / chance of an event to occur. If the probability is 0 then it indicates that the event is impossible to occur..

discuss the importance of The Age discrimination in employment act (ADEA) and its applicability in healthcare. Solution The Age Discrimination in Employment Act provides the rights to an employee so that the employer cannot refuse to hire or does not allow the discrimination if the employee is 40 or older. Through ADEA, the employee will get all the pay benefits and it will not allow the employer to classify the workers based on their age and to deprive them of their opportunities or declining them from getting promoted. The Age Discrimination in Employment Act functioning will be found similar to other federal discrimination laws and through this law who are covering can be known. In healthcare system also this ADEA law is playing an important role, in understanding the role of physicians and nurses, and how aged health care workers can provide high-quality health services in many chronic conditions. In many cases the ADEA law will protect the rights of the patients, he cannot be denied to offer any type of treatment by showing his age, and all elderly patients should get similar type of treatment..
