Question

What is the function of phosphorylase?

(a) Transfer inorganic phosphate

(b) Transfer a carboxylate group

(c) Use H2O2 as the electron acceptor

(d) Transfer amino group

This question was posed to me in an interview for internship.

My question comes from Enzymes in section Biomolecules and Catalysis of Life Sciences

Answer 1

Right choice is (a) Transfer inorganic phosphate

The explanation is: Phosphorylase is a transferase enzyme which involves a transfer of inorganic phosphate to a substrate while transcarboxylase transfer a carboxylate group and transaminase transfer amino group from amino acid to the keto acid.
