BIOD 171- Exam 2 UPDATED ACTUAL
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 ANSWER✔✔- True
T/F: Enzymes are polysaccharides that catalyze chemical reactions - CORRECT
ANSWER✔✔- False (enzymes are proteins)
What are usually metal ions and assists enzyme during the catalysis reaction? - CORRECT
ANSWER✔✔- Cofactors
Define catabolism - CORRECT 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? - CORRECT ANSWER✔✔- 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 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)
An organism that derives its energy (generates ATP) from photons of light is called -
CORRECT ANSWER✔✔- Phototrophic microorganism
An organism that derives its energy by removing electrons from elemental sulfur would be
classified as - CORRECT ANSWER✔✔- Lithotroph
A reactive intermediate would be present in which phosphorylation process - CORRECT
ANSWER✔✔- ?
