1. True or false: metabolism is a controlled set of biochemical reactions that occur in living organisms
in order to maintain life.
True
2. True or false: enzymes slow down chemical reactions to conserve energy
False, they speed up (catalyze) chemical reactions
3. The term for metal ions that assist enzymes during the catalysis reaction
Cofactors
4. What is catabolism?
The process of breaking down larger molecules into useful energy sources
5. Upon cellular injury, which metabolic process is involved during the growth and repair phases of the
cell?
Anabolism
6. An organism that obtains its energy (derives ATP) from photons of light is called a
Phototrophic microorganism
7. An organism that derives its energy by removing electrons from elemental sulfur would be classified
as a
Lithotroph
8. Describe the energy transfer process relative to both ADP and ATP
ATP has the energy (phosphate group) to donate, and ADP can accept energy in the form of a phosphate
group. Thus, ATP can be dephosphorylated (ATP-----> ADP + Pi), while ADP can be dephosphorylated into
ATP (ADP + Pi -----> ATP)
9. This phosphorylation process occurs in the mitochondria of chemotropic eukaryotes
Oxidative phosphorylation
10. The catabolism of a single molecule of glucose goes through what three transitions
The breakdown of glucose goes through 1. Glycolysis 2. Fermentation or respiration and then 3. Electron
transport chain ETC
11. True or false: in the absence of absence of oxygen fermentation produces 2 ATP
False
12. What is the primary byproduct of the TCA cycle select?
NADH and FADH2
13. True or false: in the absence of oxygen fermentation produces 2 ATP
in order to maintain life.
