Chapter 3 Note Taking Guide And Organizer

  1. 1. Chapter 3 Note Taking guide and organizer Name_________________________Date_________________Mod_______ Water Water has 4 important properties. 1. 2. 3. 4. Polarity Many of water’s _____________________ functions stem from its ___________________ structure. The _________________ and ____________________ in water __________________________ with ___________________ bonds. These atoms do not share the __________________ equally. Since the ________________ atom is bigger than the _______________________ atoms, the electrons tend to hang around the _______________________ atom more often. This gives oxygen a small _______________________ charge and the hydrogen a small ______________________ charge. A _______________________ molecule is when
  2. 2. __________________________ have ________________________ charges. Not charges like ionic bonds but smaller attractions that sometimes only water has. Being polar leads to other things like……… _____________________________ This occurs when the slightly _____________________ hydrogen atom is ________________________ to a slightly ______________________ oxygen atom of another water molecule, it is a very ___________________attraction. Draw a hydrogen bond below.
  3. 3. Cohesion This occurs when ________________________ of the same ____________________ stick to one another. What are some examples of cohesion in daily life? Adhesion This is when ___________________ that are not alike are _____________________, example, water to walls of a test tube, or plant walls When you see adhesion, think ___________________, sticky. What are some examples of adhesion? Capillarity This is when __________________ goes up a small, narrow tube like a plant stem or paper towel. _________________ makes this possible. Both adhesion and cohesion can be combined to let water do some amazing things!
  4. 4. Property of Water Definition Example Density of Water is Special!
  5. 5. Water is one of the only substances on Earth in which the _____________________ phase is less ____________________ than the ____________________phase! Because of this, life can ___________________ in many places. What would happen is this was not true? Describe. Temperature Moderation Water must ________________ or _____________________ a relatively large amount of ____________________ for its temperature to change. When water is ________________________, most of the ________________________ energy that the water initially absorbs breaks the ___________________________ between the molecules. When the _______________________ are broken, the thermal energy is _______________________ and increases the _____________________ of the molecules. Water’s ability to ______________________ large amounts of _____________________ helps keep cells at an even ________________________ despite temperature changes in the _____________________. Liquid
  6. 6. Solid Gas Fill in the blanks above to show what happens when water changes phases. Is energy released or absorbed? Are hydrogen bonds broken or formed? Carbon Compounds A _________________ atom has ___________________electrons in its outer level which means it can create ___________________ bonds with any other atoms including __________________________. This makes carbon an excellent _____________________ for many ________________________ molecules. Carbon can even form ____________________ and double and triple bonds! Functional Groups A _______________________ is a group of atoms that _______________________ the properties of the molecules they compose. _________________ is a functional group that has _________________ and _____________________attached.
  7. 7. Alcohols can cause blindness or even _____________________ when consumed. Some alcohols are important to assemble certain ______________________ in the body. Large Carbon Molecules In large _____________________ compounds, the molecules are built up from smaller, simpler molecules called ____________________. ______________________ can bind together to create larger, more complex molecules called ____________________. Large ___________________ are called ___________________. How are polymers made and broken? ______________________ link together in a _____________________________ reaction. When two _______________________ combine, ______________________ is released. When ____________________ are broken, it is called a __________________________ reaction. Water is broken into two parts and breaks the __________________ that hold the __________________________ together. Draw an example of a condensation reaction and a hydrolysis reaction below.
  8. 8. Energy Currency Life processes require __________________. This energy is available to life in the form of a compound called ___________________. ATP has ____________________ phosphates on the molecule and when one phosphate is broken off,___________________ is released. Draw an ATP molecule below. Carbohydrates
  9. 9. A _________________________ of a _______________________ is called ________________________ A monosaccharide is a ________________________ sugar. Two ___________________________ form a ___________________________. A ____________________________ is a complex molecule composed of three or more ______________________________. What are some carbs? Proteins _____________________ are _______________________ compounds made from monomers called __________________________. There are _________________________ different amino acids. The differences between the amino acids are their ___________________ groups. Two amino acids bond to form a _________________________. In a __________________________ reaction, two amino acids form a ________________________ bond called a _______________________ bond. Long chains of amino acids are called ___________________________. What are some proteins? Enzymes are a special kind of protein.
  10. 10. ______________________ are proteins that are important __________________________for chemical reactions. Enzyme reactions depend on the __________________________ between the ___________________and the _____________________________. The _________________________ is the reactant being catalyzed. Enzymes may fail to work when the _________________________ isn’t correct. Other _________________ and ____________________ are also a factor. Label the steps above. Affects on Enzymes
  11. 11. Temperature- Denature- A change in ___________________ can decrease the ability of an enzyme to function. A ___________________________________ or ______________________ can decrease the ability of an enzyme to function. Lipids ___________________ are large, non polar molecules that do not ______________________ in water. Fatty acids are _____________________ carbon chains that make up most lipids. Hydrophilic- Hydrophobic- Types of Lipids A ________________________ is composed of ____________________ molecules of fatty acids joined to an alcohol called glycerol. ______________________ have two fatty acids joined with glycerol.
  12. 12. Phospholipids are contained in the ___________________________ and form a ___________________ layer to create a barrier between the inside and outside of cell. A wax is a type of _____________________ lipid. A steroid has ___________________ carbon rings. _________________________ is an example. _____________________ are also ________________________ and very important for life. Phospholipid molecule Label the head and the tail of the molecule. Also label which is hydrophobic and which is hydrophilic. Types of Fats(Lipids) A _________________________ has all available bonds used by _______________________. Saturated fats are _________________ at room temperature and are all single bonded, straight chains
  13. 13. __________________________________ have a _______________________ bond which means not all available bonds are taken by hydrogen. _________________________ are generally _________________________ at room temperature and are healthier. Nucleic Acids ____________________________________ are large and complex organic molecules that store important _______________________ in the cell. _________________________ stores and transfers information to make _______________________. ______________________________ contains information that is essential for cell activities. Both ____________________ and ________________________ are composed of ____________________________ called __________________________. A nucleotide has _________________________components: a _____________________________ group, a _________________________ and a ___________________________. Essential Questions 1. Describe the structure of the water molecule. 2. What are two properties of water that are caused by hydrogen bonding?
  14. 14. 3. What is an organic compound? 4. Define functional group and give an example. 5. How does a polymer form? 6. How does a polymer break down? 7. What are the 4 classes of organic compounds? Give an example of each.
