BIOD 171 UPDATED ACTUAL EXAM 2 Questions
And CORRECT Answers
True or False: Metabolism is a controlled set of biochemical reactions that occur in living organisms in to
maintain life - CORRECT ANSWERS True
T/F: Enzymes are polysaccharides that catalyze chemical reactions - CORRECT ANSWERS False
(enzymes are proteins)
What are usually metal ions and assists enzyme during the catalysis reaction? - CORRECT
ANSWERS Cofactors
Define catabolism - CORRECT ANSWERS 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 ANSWERS The anabolic process would be active as it is involved in the building up of
small complexes into larger complexes
Describe energy transfer process relative to both ATP and ADP - CORRECT ANSWERS 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)
An organism that derives its energy (generates ATP) from photons of light is called - CORRECT
ANSWERS Phototrophic microorganism
An organism that derives its energy by removing electrons from elemental sulfur would be classified as -
CORRECT ANSWERS Lithotroph
