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
