BIOD 171 Exam 2 Questions with Correct
Answers
True or False: Metabolism is a controlled set of biochemical reactions that occur in
living organisms in to maintain life
True
T/F: Enzymes are polysaccharides that catalyze chemical reactions
False (enzymes are proteins)
What are usually metal ions and assists enzyme during the catalysis reaction?
Cofactors
Define catabolism
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?
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
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
Phototrophic microorganism
