True or False: Metabolism is a controlled set of biochemical reactions that occur in living or-
ganisms in to maintain life - ANSWER True
T/F: Enzymes are polysaccharides that catalyze chemical reactions - ANSWER False (en-
zymes are proteins)
What are usually metal ions and assists enzyme during the catalysis reaction? - ANSWER
Cofactors
Define 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 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 - ANSWER ATP has the en-
ergy (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 - AN-
SWER Phototrophic microorganism
An organism that derives its energy by removing electrons from elemental sulfur would be
classified as - ANSWER Lithotroph
