Summary Introduction
Introduction:
The process of breaking down of the glucose into two molecules of pyruvate is known as glycolysis. This cycle plays a vital role in the production of energy in the body. The pyruvate is then converted into acetyl CoA (coenzyme-A) and takes part in the Krebs’s cycle.

Identify the conversion which is not involved in glycolysis.
a.Glucose to glucose 6-phosphate by hexokinase
b.Triose phosphate to 2-phosphoglycerate by phosphoglyceromutase
c.PEP to pyruvic acid by pyruvate kinase
d.Sucrose to glucose and fructose by invertase
During strenuous exercise, the NADH formed in the glyceraldehyde 3-phosphate dehydrogenase reaction in skeletal muscle must be reoxidized to NAD+ if glycolysis is to continue. The most important reaction involved in the reoxidation of NADH is:
a. dihydroxyacetone phosphate → glycerol 3-phosphate
b. glucose 6-phosphate → fructose 6-phosphate
c. isocitrate → α-ketoglutarate
d. oxaloacetate → malate
e. pyruvate → lactate
The steps of glycolysis between glyceraldehyde 3-phosphate and 3-phosphoglycerate involve all of the following except:
a. ATP synthesis.
b. catalysis by phosphoglycerate kinase.
c. oxidation of NADH to NAD+.
d. the formation of 1,3-bisphosphoglycerate.
e. utilization of Pi.
