Verified step by step guidance

Understand the concept of enzyme concentration in the context of enzyme kinetics. The total concentration of enzyme in a reaction is the sum of the free enzyme concentration and the enzyme-substrate complex concentration.

Identify the terms: [E] represents the concentration of free enzyme, and [ES] represents the concentration of the enzyme-substrate complex.

Recall that the total enzyme concentration is the sum of the enzyme in its free form and the enzyme bound to the substrate. This is expressed as [E] + [ES].

Evaluate each option given in the problem to determine which one correctly represents the total concentration of enzyme.

Conclude that the correct representation of the total enzyme concentration is [E] + [ES], as it accounts for both the free enzyme and the enzyme bound to the substrate.
