PORTAGE LEARNING BIOD 171
MICROBIOLOGY LAB NOTEBOOK
PRACTICE TEST BANK 2026 TESTED
QUESTIONS WITH ANSWERS GRADED A+
⩥ True or false: enzymes slow down chemical reactions to conserve
energy. Answer: false, they speed up (catalyze) chemical reactions
⩥ The term for metal ions that assist enzymes during the catalysis
reaction. Answer: cofactors
⩥ What is catabolism?. 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.. Answer: anabolism
⩥ An organism that obtains its energy (derives ATP) from photons of
light is called a __________________. Answer: phototrophic
microorganism
⩥ An organism that derives its energy by removing electrons from
elemental sulfur would be classified as a ____________. Answer:
Lithotroph
, ⩥ Describe the energy transfer process relative to both ADP and ATP.
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. Answer: oxidative phosphorylation
⩥ The catabolism of a single molecule of glucose goes through what
three transitions. 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. Answer: false
⩥ what is the primary byproduct of the TCA cycle select. Answer:
NADH and FADH2
⩥ True or false: in the absence of oxygen fermentation produces 2 ATP.
Answer: False, it does not produce any additional ATP
