Question

Categorize each enzyme based on its specific function in glycolysis, gluconeogenesis, or both pathways.a. Triose phosphate isomerase b. Glucose 6-phosphatase c. Hexokinase d. Fructose I ,6-bisphosphatase e. Phosphofructokinase f. Pyruvate kinase

Answer 1

Answer:

a. Triose phosphate isomerase glycolysis

b. Glucose 6-phosphatase gluconeogenesis

c. Hexokinase  glycolysis & gluconeogenesis

d. Fructose I ,6-bisphosphatase gluconeogenesis

e. Phosphofructokinase glycolysis

f. Pyruvate kinase glycolysis

Explanation:

Triose phosphate isomerase is a protein that functions as an enzyme, and takes part in glycolysis, in the interconversion of dihydroxyacetone phosphate and D-glyceraldehyde 3-phosphate. Glucose 6-phosphatase is also a protein that works as an enzyme, it hydrolyzes glucose 6-phosphate given glucose free as a result. Hexokinase is a protein too, and is part of a wider group of enzymes. It forms hexose phosphate by phosphorylating hexoses (six-carbon sugars). Fructose I ,6-bisphosphatase is an enzyme too, and it tranforms fructose-1,6-bisphosphate into fructose 6-phosphate. Phosphofructokinase is an enzyme too, that works in changing a phosphoryl group from ATP to fructose-6-phosphate (F6P). Pyruvate kinase is an enzyme that catalyzes the conversion of ADP tp ATP and phosphoenolpyruvate to pyruvate.
