BIOD 171- Exam 2 Questions and Answers With Complete
Solutions rated A+
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
, An organism that derives its energy by removing electrons from elemental sulfur would be
classified as - ✔✔Lithotroph
A reactive intermediate would be present in which phosphorylation process - ✔✔?
The chemical compound losing the phosphate group is referred to as the - ✔✔phosphorylated
reactive intermediate
The catabolism of a single molecule of glucose goes through what 3 distinct transitions -
✔✔Glycolysis, Fermentation or Respiration, then the ETC- electron transport chain
What is the most energetic transition in the catabolism of glucose? - ✔✔The electron transport
chain yields 34 ATP while both glycolysis and fermentation (or respiration) each yield only 2 ATP
Identify the reactants of the following chemical equation:
Glucose + 2NAD+ -> 2 NADH + 2 Pyruvate + 2ATP - ✔✔The reactants are to the left of the
arrow: Glucose and 2NAD+
The presence of what molecule 'signals' to the cell that glycolysis is about to start? -
✔✔Glucose-6-phosphate (G6P)
