    • 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
    • __________________________ 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.
    • 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!
    • Property of Water Definition Example Density of Water is Special!
    • 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
    • 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.
    • 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.
    • 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
    • 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.
    • ______________________ 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
    • 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.
    • 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
    • __________________________________ 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?
    • 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.
