171 BIOD Exam 2026 Questions and
Answers
True or false: metabolism is a controlled set of biochemical reactions that occur in
living organisms in order to maintain life. - Correct answer-True
True or false: enzymes slow down chemical reactions to conserve energy - Correct
answer-false, they speed up (catalyze) chemical reactions
The term for metal ions that assist enzymes during the catalysis reaction - Correct
answer-cofactors
What is catabolism? - Correct answer-The process of breaking down larger
molecules into useful energy sources
Upon cellular injury, which metabolic process is involved during the growth and
repair phases of the cell. - Correct answer-anabolism
An organism that obtains its energy (derives ATP) from photons of light is called a
__________________ - Correct answer-phototrophic microorganism

, An organism that derives its energy by removing electrons from elemental sulfur
would be classified as a ____________ - Correct answer-Lithotroph
Describe the energy transfer process relative to both ADP and ATP - Correct
answer-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)
This phosphorylation process occurs in the mitochondria of chemotropic
eukaryotes - Correct answer-oxidative phosphorylation
The catabolism of a single molecule of glucose goes through what three transitions
- Correct answer-The breakdown of glucose goes through 1. glycolysis 2.
fermentation or respiration and then 3. electron transport chain ETC
True or false: in the absence of absence of oxygen fermentation produces 2 ATP -
Correct answer-false
what is the primary byproduct of the TCA cycle select - Correct answer-NADH
and FADH2
True or false: in the absence of oxygen fermentation produces 2 ATP - Correct
answer-False, it does not produce any additional ATP
