Question

enzymes are biological catalysts. what aspect of a reaction do they lower, thereby increasing the reaction rate dramatically?
a) $v_{max}$
b) $k_{m}$
c) equilibrium
d) activation energy

Explanation:

Enzymes, as biological catalysts, function by reducing the minimum energy required for a reaction to start, which speeds up the reaction rate without affecting equilibrium, $V_{max}$, or $K_m$. This required energy is called activation energy.

Answer:

d) Activation energy
