BIOD171 Portage Microbiology Final
Exam Questions And Answers Latest
Update
What various functions do proteins have in a cell - - correct answer
✅Proteins may facilitate the movement of materials in or out of a
cell.
Some can act as enzymes that catalyze, or speed up, biochemical
processes.
Others play a structural role while other proteins, such as filaments,
enable movement.
What are the main morphologies of bacteria? - - correct answer
✅Bacteria can be described as coccus (round/spherical),
bacillus (rod),
vibrio (curved rod)
spirillum (spiral/corkscrew).
What are the 4 main classifications of Eukarya - - correct answer
✅Animalia, Plantae, Fungi or Protista
What are the primary cellular organelles described in this module?
Be sure to know the roles of each. - - correct answer ✅Ribosomes
(protein synthesis)
ER (site of protein synthesis)

Exam Questions And Answers Latest
Update
Golgi (protein modification and distribution) lysosomes (waste
disposal),
mitochondria (ATP generation)
chloroplasts (plants only; site of photosynthesis).
True or False: Enzymes are polysaccharides that catalyze chemical
reactions. - - correct answer ✅False. Enzymes are proteins
What are usually metal ions known to assists enzyme during the
catalysis reaction? - - correct answer ✅Cofactors
Define catabolism - - correct answer ✅the breakdown of complex
molecules in living organisms, release of energy
Upon cellular injury, which metabolic process is involved during the
growth and repair phases of the cell? - - correct answer ✅The
anabolic process would be active as it is involved in the building up
of small complexes into larger complexes.
Describe the energy transfer process relative to both ATP and ADP. -

group. Thus, ATP can be reduced (ATP →ADP + Pi) while ADP can be
built into ATP (ADP + Pi →ATP).
An organism that derives its energy (generates 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
A reactive intermediate would be present in which phosphorylation
process? - - correct answer ✅The chemical compound losing the
phosphate group is referred to as the phosphorylated reactive
intermediate.

✅NADH and FADH2
True or False. The reactants of the TCA cycle directly enter and fuel
the electron transport system. - - correct answer ✅False.
