BIOD171 Portage Microbiology Final Exam Questions and
Latest Answers
Question 1
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.
Question 2
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).

,Question 3
What are the 4 main classifications of Eukarya
Correct Answer
Animalia, Plantae, Fungi or Protista
Question 4
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)
Golgi (protein modification and distribution) lysosomes (waste disposal),
mitochondria (ATP generation)
chloroplasts (plants only; site of photosynthesis).
Question 5
True or False: Enzymes are polysaccharides that catalyze chemical reactions.
Correct Answer
False. Enzymes are proteins

, Question 6
What are usually metal ions known to assists enzyme during the catalysis reaction?
Correct Answer
Cofactors
Question 7
Define catabolism
Correct Answer
the breakdown of complex molecules in living organisms, release of energy
Question 8
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.
Question 9
Describe the energy transfer process relative to both ATP and ADP.
Correct Answer
ATP has the energy (phosphate group) to donate while ADP can accept energy in the form of a phosphate group. Thus,
ATP can be reduced (ATP →ADP + Pi) while ADP can be built into ATP (ADP + Pi →ATP).
