Question

enzymes are biological catalysts. what aspect of a reaction do they lower, thereby increasing the reaction rate dramatically? a) km b) equilibrium c) activation energy d) vmax

Explanation:

Enzymes are biological catalysts that increase the rate of a reaction by lowering the activation - energy required for the reaction to occur. They do not affect the equilibrium of the reaction, $K_m$ is a measure of the affinity of an enzyme for its substrate and $V_{max}$ is the maximum rate of the enzyme - catalyzed reaction. The key factor they lower is activation energy.

Answer:

c) Activation energy
