Microbiology Exam 2 Exam Preparation Complete Study Guide with Solution 2025/ 2026 Microbiology Exam 2.pdf
1) T/F: Metabolism is a controlled set of biochemical reactions that
occur in living organisms in order to maintain life.
True
2) T/F: Dark reactions can occur in the presence or absence of light:
True bc of the Calvin Cycle
3) T/F: Enzymes slow down chemical reactions to conserve energy.
False- Enzymes CATALYZE chemical reactions
4) T/F: The absence of oxygen fermentation produces 2 ATP.
False; fermentation only reduces NADH back to NAD+
5) T/F: During fermentation one means of eliminating pyruvate is by
converting it into lactic acid.
True
6) T/F: The reactants of the TCA cycle directly enter and fuel the ETS.
False; the products of the TCA cycle enter and drive the production
of ATP by ETS.
7) T/F: The B-oxidation pathway is responsible for the anabolism of
fatty acid chains.
False; responsible for the CATABOLISM of fatty acid chains.
8) T/F: Plants, algae and bacteria all contain chloroplasts.
False; chloroplasts are specific to algae and plants only.
9) T/F: The Calvin Cycle must occur in the absence of light.
False; does not have to because dark reactions do not require
darkness to occur.
10) T/F: As movement requires energy, metabolism can be defined
as a controlled set of biochemical reactions that occur in only motile
organisms in order to maintain life.
False; metabolism occurs in all living organisms, not just ones that
move.
11) T/F: Enzymes are polysaccharides that catalyze chemical
reactions.
