Question
Chapter 6.14, Problem 2MQ
Summary Introduction
The enzyme regulation occurs with the presence of two sites in an allosteric enzyme. The allosteric site is responsible for the feedback inhibition of biosynthetic pathway. The active site is responsible for the catalytic activity of an enzyme. The allosteric site is responsible for the regulation of an enzyme.
