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.
