BIBC 102 Practice Final Exam Key
1). The following are basic questions regarding glycolysis:
a. Name all the intermediates of the glycolytic pathway:
Glucose, glucose-6-P, fructose 6-P, fructose-1,6-bis-P, DHAP/GAP, 1,3-bpg,
3pg, 2pg, PEP, Pyruvate
(Goodness, Gracious, Father, Franklin, Did/Go, By, Picking, Pumpkins, (to)
b. Name all the enzymes involved in the glycolytic pathway:
Hexokinase, phosphohexoisomerase, phosphofructokinase, aldolase,
triosphosphate isomerase, GAPDH, PGK, phosphoglucomutase, enolase,
c. Which steps are high energy commitment steps (irreversible)?
Glucose to glucose-6-P, fructose 6-P to fructose-1,6-bP, and PEP to pyruvate
2.) You just ran a 4 minute mile like Dr. Coleman. Which metabolic catabolic process
proceeds during your run?
During your run your body needs to regenerate
in order keep glycolysis
going. What anaerobic pathway is used to accomplish this?
Lactic acid fermentation
The product of this pathway is a three carbon molecule called
molecule is converted back into pyruvate by the enzyme
Diagram the PDH (we’re looking for something along the lines of the diagram in
