Question

A researcher claims that the epinephrine signaling pathway controls a catabolic process in muscle cells

Answer 1

Answer:

Glycogen phosphorylase catalyzes the conversion of glycogen to glucose-1-phosphate.

Explanation:

Glycogen phosphorylase catalyzes glucose-1-phosphate release by phosphorolysis from the terminal residue of a non-reducing end of a glycogen branch. A molecule of inorganic phosphate attacks the C1 side of a α(14) glycosidic bond, leaving in the glycogen polymer a hydroxyl group on C4.
