Adipose-Specific Enzymes: PEPCK and Pyruvate Carboxylase Isozymes

BIOCHM-P1NTME

Adipose cells express both phosphoenolpyruvate carboxykinase (PEPCK) and pyruvate carboxylase.

Why?

A

These enzymes are needed for glycolysis to occur in adipose tissue.

B

These enzymes are needed to make glucose (gluconeogenesis) in adipose tissue.

C

These enzymes are needed to make glycerol (glyceroneogenesis) in adipose tissue.

D

These enzymes are needed for lipogenesis to occur in adipose tissue.

E

These enzymes are needed to produce molecules needed for shuttling glycerol and fatty acids across the cell membrane.
