Match the pathway with its most highly regulated enzyme.
fructose 1,6 biphosphate phosphatase
glucose-6-phosphate dehydrogenase
glycogen synthase
phosphofructokinase 1
acetyl coa carboxylase
carbamoyl phosphate synthetase
a. glycogenesis
b. glucogenesis
c. urea cycle
d. fatty acid synthesis
e. glycolysis
f. pentose phosphate pathway

A.Glycogenesis: Glycogen synthase

B. Glucogenesis: Fructose 1,6 biphosphate phosphatase

C. Urea cycle  : Carbamoyl phosphate synthetase

D.Fatty acid synthesis:  Acetyl CoA carboxylase

E.Glycolysis : Phosphofructokinase 1

F. Pentose phosphate pathway: Glucose-6-phosphate dehydrogenase

Explanation:

A. Glycogen synthase converts glucose into glycogen during glycogenesis.

B. Fructose 1,6 biphosphate phosphatase catalyzes condensation of dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-phosphate during glucogenesis.

C. Carbamoyl phosphate synthetase I catalyses production of arbamoyl phosphate during urea cycle.

D. Carboxylase controls fatty acid metabolism.

E. The phosphofructokinase 1 is an important enzyme that regulate  formation of two-phosphate sugar molecules during glycolysis.

F. Glucose-6-phosphate dehydrogenase participates in the pentose phosphate pathway. This pathway gives reducing energy to cells.
