Question

How does the phosphorylation state of serine residues affect the catalytic activity of glycogen phosphorylase?

Accepted Answer

Phosphorylated serine residues increase catalytic activity by favoring the r state.

Answer

Phosphorylated serine residues decrease catalytic activity by favoring the t state.

Answer

Phosphorylated serine residues decrease catalytic activity by favoring the r state.

Answer

Phosphorylated serine residues have no effect on catalytic activity.
