Chapter 12, Problem 13E

(a)

Summary Introduction

To explain: The substrate that has the higher apparent affinity for the enzyme chymotrypsin.

Concept introduction: Enzymes are biological protein catalysts which alter the speed of the reaction in the biological system. K_M is the Michaelis-Menton constant. V_max is the maximum velocity with which the enzyme catalyzes the reaction.
