Patients in shock experience decreased delivery of O2 to tissues, decreased activity of the pyruvate dehydrogenase complex, and increased anaerobic metabolism. Excess pyruvate is converted to lactate, which accumulated in tissues and in the blood, causing lactic acidosis. Since O2 is not a reactant or product of the citric acid cycle, why do low levels of O2 decrease the activity of the pyruvate dehydrogenase complex? Solution pyruvate dehydrogenase complex is found in only mitochondria ( we know that mitochondria is the power house of the cell as well as the cell respiration will takes place means what ever the enzymes present in mitochondria they are more active at high oxygen level ) this enzyme requires five cofactors namely TPP,lipoamide,FAD,coenzyme A,and NAD + the conversion of pyruvate to acetyl CoA finished when reduced lipoamide is converted to oxidized lipamide .

ELECTRON TRANSPORT PRESENTATION.pptx
The document discusses oxidative phosphorylation and the electron transport chain. It explains that NADH and FADH2 are oxidized through enzyme complexes in the inner mitochondrial membrane. As electrons flow through this chain, energy is used to pump hydrogen ions into the intermembrane space, creating a proton gradient. When hydrogen ions diffuse back through ATP synthase pores, ADP is phosphorylated to ATP, capturing the energy released. Defects in these complexes can cause fatal mitochondrial disorders.

Bioenergetics
Bioenergetics is the study of energy changes in biochemical reactions and biological systems. The laws of thermodynamics govern energy changes. ATP is the primary energy currency in cells. It is produced through oxidative phosphorylation where the energy released from redox reactions is used to pump protons across the mitochondrial inner membrane, creating a proton gradient. ATP synthase uses this proton gradient to phosphorylate ADP, producing ATP. Diseases can result from defects in the electron transport chain or oxidative phosphorylation.
Citric Acid Cycle
The citric acid cycle is a series of chemical reactions in the mitochondria that break down acetyl groups from carbohydrates, fats, and proteins into carbon dioxide, generating reduced coenzymes used in oxidative phosphorylation to produce ATP. Pyruvate is converted to acetyl-CoA by the pyruvate dehydrogenase complex, then the citric acid cycle oxidizes acetyl-CoA in 8 steps, producing NADH, FADH2, and GTP or ATP while releasing CO2. This cycling of intermediates allows for the efficient breakdown of fuels to generate energy.
Respiration
1) Respiration requires oxygen to fully oxidize nutrients and produce more ATP. It involves glycolysis, the Krebs cycle in mitochondria, and the electron transport chain, where ATP is generated by oxidative phosphorylation.
2) During aerobic respiration, glucose breakdown yields up to 36 ATP molecules, with most ATP generated in the mitochondria. Anaerobic respiration like fermentation only yields 2 ATP per glucose without oxygen.
3) The structure of mitochondria, with its inner and outer membranes, matrix, and cristae, allows for compartmentalization of redox reactions and generation of a proton gradient across the inner membrane for ATP production via chemiosmosis.
Bioprocess ppt
The document summarizes two types of fermentation: alcoholic fermentation and lactic acid fermentation. In alcoholic fermentation, yeast and microorganisms ferment glucose to ethanol and CO2 through glycolysis and subsequent conversion of pyruvate to acetaldehyde and ethanol. In lactic acid fermentation, when tissues cannot be supplied with oxygen, NAD+ is regenerated through the reduction of pyruvate to lactic acid by lactate dehydrogenase. Lactic acid fermentation allows extraction of some energy from glucose in the form of ATP.

Tca cycle b.pharm
The document summarizes the three stages of catabolism:
1. Pyruvate is converted to acetyl-CoA in the mitochondria by the pyruvate dehydrogenase complex. This is the committed step to the citric acid cycle.
2. The pyruvate dehydrogenase complex contains three enzymes and requires five cofactors including thiamine pyrophosphate and Coenzyme A.
3. Acetyl-CoA then enters the citric acid cycle, which occurs in the mitochondrial matrix and fully oxidizes acetyl-CoA, producing carbon dioxide and reducing equivalents like NADH and FADH2.
11 krebs cycle
The Pyruvate Dehydrogenase complex catalyzes the conversion of pyruvate to acetyl-CoA and includes three enzymes: E1, E2, and E3. E1 uses thiamine pyrophosphate to oxidize pyruvate and transfer the acetyl group to E2. Lipoic acid covalently attached to E2 carries the acetyl group to E3, where it is transferred to CoA to form acetyl-CoA. Electrons are transferred through the complex to NAD+ to form NADH. The complex is regulated by phosphorylation/dephosphorylation of E1 and by product inhibition by NADH and acetyl-CoA. Acetyl-CoA produced

Fate of Pyruvic acid in biochemistry pharm d notes.pptx
Pyruvic acid undergoes decarboxylation in the mitochondrion, catalyzed by the pyruvate dehydrogenase complex. This reaction prepares pyruvate for entry into the citric acid cycle by releasing carbon dioxide and extracting high-energy electrons. Alternatively, pyruvate can be reduced to lactate by lactate dehydrogenase under anaerobic conditions, such as in exercising muscle, or it can be reduced to ethanol by microorganisms using pyruvate decarboxylase and other enzymes.
BT631-28-Dehydrogenases
Dehydrogenases are oxidoreductase enzymes that catalyze the removal of hydrogen from substrates through oxidation-reduction reactions. They transfer hydrogen from substrates to acceptors like NAD+/NADP+ or flavin enzymes. There are several classes of dehydrogenases that act on different substrate groups like alcohol, aldehyde, ketone, etc. Alcohol dehydrogenase catalyzes the interconversion of alcohol and aldehyde with NAD+/NADH involved. It has important roles in metabolism and toxin removal in organisms. Excessive ethanol consumption can disrupt metabolic pathways and cause dangerous conditions due to changes in NADH and lactate levels.

Carbohydrate metabolism involves the breakdown of glucose and other carbohydrates to produce energy in the form of ATP. Glucose is either stored as glycogen, metabolized through glycolysis to produce energy, or stored as fat. Pyruvate produced through glycolysis can be converted to lactate through anaerobic metabolism or enter the mitochondria to undergo aerobic metabolism through the TCA cycle and oxidative phosphorylation, producing the most ATP. Volatile fatty acids produced by gut bacteria are also metabolized through these pathways to produce energy. Organisms with high energy demands increase various physiological capacities to produce ATP through carbohydrate and lipid metabolism.

Let phi: R rightarrow S be a surjective homomorphism from the ring R to the ring S. Prove that if T is a subring of R, then the set W= {b S such that b = phi (c) for some c T } is a subring of S. [Be specific of how and where you use that T is a subring of R.]
Solution
Let a, b in W. Then a= phi(r) for some r in T and b = phi(t) for some t in T. Now to show a+b is in W, notice that a+b = phi(r)+phi(t)=phi(r+t). Since T is a subring and r and t are in T, then r+t is in T too. So a+b is in W. To show a*b is in W, notice that since T is a subring, r*t is in W. So a*b = phi(r)phi(t)=phi(rt). SInce rt is in T, a*b is inW. To show that -a is in W, notice that since T is a subring, if r is in T, so is -r. So, phi(-r) = -phi(r) = -a. Hence -a is in W. Finally, since T is a subring, 0 is in T. So 0 = phi(0), so 0 is in W too. By the subgring criterion, W is a subring. Please rate :).

Let phi: R rightarrow S be a surjective homomorphism from the ring R to the ring S. Prove that if T is a subring of R, then the set W= {b S such that b = phi (c) for some c T } is a subring of S. [Be specific of how and where you use that T is a subring of R.]
Solution
Let a, b in W. Then a= phi(r) for some r in T and b = phi(t) for some t in T. Now to show a+b is in W, notice that a+b = phi(r)+phi(t)=phi(r+t). Since T is a subring and r and t are in T, then r+t is in T too. So a+b is in W. To show a*b is in W, notice that since T is a subring, r*t is in W. So a*b = phi(r)phi(t)=phi(rt). SInce rt is in T, a*b is inW. To show that -a is in W, notice that since T is a subring, if r is in T, so is -r. So, phi(-r) = -phi(r) = -a. Hence -a is in W. Finally, since T is a subring, 0 is in T. So 0 = phi(0), so 0 is in W too. By the subgring criterion, W is a subring. Please rate :).

Please help me- I understand that iron(III) chloride is the correct na.docx
Please help me. I understand that iron(III) chloride is the correct name for FeCl3 . However I am confused. The subscript is clearly next to the chloride. Yet the Roman numeral three is next to the iron...
PartA Which one of the following is the correct name for FeCl3? View Available Hint(s) iron trichloride iron chloride iron(Ill) chloride iron chlorine Previous Answers Correct The iron ion in this compound carries a +3 charge, and that needs to be sho Provide Feedback 10
Solution
FeCl3 means three -Cl atoms are attached to Fe atom.
Each -Cl carries -1 charge so the charge for three -Cl are -3.
so in order to balance the negative charge, the charge on Fe should be +3 to get a neutral FeCl3 complex.
so the charge on Fe is +3 and it is represented in brackets next to Fe and the name is iron(III)chloride

Please help me solve this I already asked this question and someone solved it incorrectly. Thank you.
Solution
given,
concentration of NH 4 NO 2 = 1.10 M
in volume = 2.20 L
step1
thus, moles of NH 4 NO 2 = 1.10 x 2.20 = 2.42 moles
step2
1 mole of NH 4 NO 2 can form 1 mol of N 2
2.42 moles of NH 4 NO 2 can form 2.42 moles of N 2
step3
pressure is only due to N 2 gas
p = nRT / v
p = 2.42 x 0.0821 x 298 / 2.20
p = 26.91 atm
step4
pressure in 10 L
p = nRT / v
p = 2.42 x 0.0821 x 25 /10
p = 5.92 atm
step5
change in pressure = 26.91 - 5.92 = 20.99 atm or (21 atm)

Please give me two thoughtful paragraphs for two of the following ques.docx
The CEO of Baldwin Company reported on 4 financial ratios to analysts instead of the 11 ratios prepared by the controller. Reporting fewer ratios allows the CEO to selectively disclose information that paints the company in a positive light. However, this risks misleading analysts and investors by omitting other important metrics, and could damage the company's reputation if seen as an attempt to hide negative financial details. The controller, who prepared all 11 ratios for the board, should advise caution to prevent legal and credibility issues from selective disclosure of only favorable information.

please explain tooSolutionVHDL (Very High Speed IC Hardware descriptio.docx
please explain too
Solution
VHDL (Very High Speed IC Hardware description Language) is one of the standard hardware description language used to design digital systems. VHDL can be used to design the lowest level (gate level) of a digital system to the highest level (VLSI module). VHDL though being a rigid language with a standard set of rules allows the designer to use different methods of design giving different perspectives to the digital system. Other than VHDL there are many hardware description languages available in the market for the digital designers such as Verilog, ABEL, PALASM, CUPL, and etc but VHDL and Verilog are the most widely used HDLs. The major difference between hardware description programming languages and others is the integration of time. Timing specifications are used to incorporate propagation delays present in the system

Please explain how HDFS provides redundancy for stored dataSolutionHDF.docx
Please explain how HDFS provides redundancy for stored data
Solution
HDFS is designed to reliably store very large files across machines in a large cluster. It stores each file as a sequence of blocks; all blocks in a file except the last block are the same size. The blocks of a file are replicated for fault tolerance. The block size and replication factor are configurable per file. An application can specify the number of replicas of a file. The replication factor can be specified at file creation time and can be changed later. Files in HDFS are write-once and have strictly one writer at any time. The NameNode makes all decisions regarding replication of blocks. HDFS uses rack-aware replica placement policy. In default configuration there are total 3 copies of a datablock on HDFS, 2 copies are stored on datanodes on same rack and 3rd copy on a different rack.

Please answer questions 1-4- thank you!Solution1- Acids are the conpou.docx
Please answer questions 1-4, thank you!
Solution
1. Acids are the conpounds which give H+ ions in the aquous solution. Bases give OH- ions innthe aquous solutions.
Acids are the proton donors and bases are the proton acceptors.
2. Litmus paper is the most common indicator used in the labs. Litmus turns green ti basic and red to acidic. Other is methyl ornage shows pink in acidic medium and shows yellow in basic and phenophthaline etc.
3. HClO is an acid it can give H+ ions i.e proton.
Na2CO3 is formed by H2CO3 and NaOH. So it is a neutrilisation of weak acid with strong base so it will be a basic salt.
H2O is neutral.
H3BO3 is boric acid. As the name suggests its an acid it can donate H+.
4. Anything less than pH=7 is acidic uptill 1.
pH=7 is neutral
pH>7 is basic uptill 14

Please answer bothSolution18- Nature chose polyamides to form proteins.docx
Nature chose polyamides to form proteins because polyamides are made through condensation reactions of amino acids that eliminate water molecules. These protein structures have chains stabilized by hydrogen bonding between nitrogen atoms on one chain and oxygen atoms from the carbonyl groups on another chain. This hydrogen bonding stabilizes the protein structure in a way that is not possible with esters. Nature selects monosubstituted amides over disubstituted amides for proteins due to disubstitution increasing steric effects that destabilize the protein chains and disrupt important hydrogen bonding between chains, which stabilize the primary, secondary, and quaternary protein structures.

Patients in shock experience decreased delivery of O2 to tissues- decr.docx
- 1. Patients in shock experience decreased delivery of O2 to tissues, decreased activity of the pyruvate dehydrogenase complex, and increased anaerobic metabolism. Excess pyruvate is converted to lactate, which accumulated in tissues and in the blood, causing lactic acidosis. Since O2 is not a reactant or product of the citric acid cycle, why do low levels of O2 decrease the activity of the pyruvate dehydrogenase complex? Solution pyruvate dehydrogenase complex is found in only mitochondria ( we know that mitochondria is the power house of the cell as well as the cell respiration will takes place means what ever the enzymes present in mitochondria they are more active at high oxygen level ) this enzyme requires five cofactors namely TPP,lipoamide,FAD,coenzyme A,and NAD + the conversion of pyruvate to acetyl CoA finished when reduced lipoamide is converted to oxidized lipamide
