#Unit 1. Molecules and their Interaction Relevant to Biology

Choose the correct statement of the following

a. In general, high acetyl-CoA or citrate are present, or when a high proportion of the cell’s adenylate is in the form of ATP, gluconeogenesis is favored.

b. When the level of AMP increases, it promotes glycolysis by stimulating PFK-1 by inhibiting FBPase-1

c. Phosphorylation of fructose 6-phosphate, catalysed by phosphofructokinase-2 (PFK-2)

d. Glucagon increases the cellular level of fructose 2,6 bisphosphate, stimulating glycolysis and inhibiting gluconeogenesis.
