Macromolecule, Enzyme, Water Review
1. What type of bonds keep hydrogen and oxygen bound together in a single water molecule?
Polar covalent
2. What type of bond keeps individual water molecules attracted to each other? Draw an
example of this bond.
Hydrogen
3. How do the bonds mentioned in question 1 and 2 affect adhesion? (Be sure to define
adhesion in your answer).
Water is attracted to other surfaces. It is attracted to other surfaces because it is polar.
4. How do the bonds in question 1 and 2 affect cohesion? (Be sure to define cohesion in your
answer).
Water is attracted to other water molecules. Hydrogen bonds keep water attracted to itself.
5. What are the six elements necessary of life? For something to be considered organic, which
of these elements MUST be present?
Carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur
For something to be considered organic, it needs CARBON
6. Label the reactants and products on the chemical equation below.
Reactants
Product
In
7. In this equation the masses are equal (you can count the number of atoms on each side). Is
mass conserved in all chemical reactions? Why?
Yes, the law of conservation of mass. Mass (matter) cannot be created or destroyed.
8. Think back to your toothpickase lab. You broke your toothpicks at a fairly steady rate. Would
that rate change because more toothpicks were added for you to break? Why?
*Remember, that unlike your hands, enzymes do not “get tired”.
NO! Adding more substrate does not change the speed at which a reaction happens. It will still
move just as fast/slow.
Would the rate of reaction change if more toothpickase was added to your reaction? Why?
YES! You have twice as much enzyme to break up the substrate.
9. Label the three particles found in an atom on the picture below. Pay attention to location and
charge.
Electron- outer and negative
Proton- positive and in the nucleus
Neutron- no charge and in the nucleus
10. Write in one of the four macromolecules that corresponds with the description.
____​ Nucleic Acids​___________ Used to store genetic information.
____​ Protein ​___________Made of amino acids.
___​ lipids ​____________Used for long term energy storage.
____​ lipids ​___________Coats the outside of your cells.
____​ Nucleic acids ​___________Found in DNA.
____​ carbohydrates ​___________Quick sources of energy.
____​ carbohydrates ​___________Often broken down into glucose.
____​ protein ​___________Used to catalyze reactions.
11. Write in the monomer and atomic elements of each of the following macromolecules.
a. Protein: ____​ amino acids _
​ ____________, ______​ CHON​______________
b. Nucleic Acids__________​ nucleotides _
​ ______, ____​ CHNOP ​________________
c. Carbohydrates_____​ monosacharids​____________, ____​ CHO ​________________
d. Lipids____​ fatty acid and glycerol _
​ ____________, _____​ CHO​_______________
12. Why do all enzymatic reactions look like this?
Time
Eventually run out of substrate. All the product that can be made is made.
13. What does it mean if an enzyme is denatured? List two things that could denature an
enzyme.
Active site altered to be non functional. High temp, change in ph.
