Question

What is the impact of serine phosphorylation on the interconversion between phosphorylase a and b forms?

Accepted Answer

Phosphorylation converts phosphorylase b to phosphorylase a, increasing catalytic activity.

Answer

Phosphorylation converts phosphorylase a to phosphorylase b, increasing catalytic activity.

Answer

Phosphorylation converts phosphorylase a to phosphorylase b, decreasing catalytic activity.

Answer

Phosphorylation has no effect on the interconversion between phosphorylase forms.
