Question

Enzymes are a crucial component in chemical reactions needed for the human body. How does the reduction in activation energy by an enzyme affect a chemical reaction?

A) The reaction proceeds at a faster rate.
B) The products are not stable.
C) Less energy is gained from the reaction.
D) The reaction is less efficient when the enzyme is present.

Answer 1

Enzymes lower the activation energy of a chemical reaction, allowing it to proceed at a faster rate.

Step-by-step explanation:

An enzyme functions by lowering the activation energy of a chemical reaction. Activation energy is the energy needed to start a chemical reaction. Enzymes do this by binding to the reactant molecules and holding them in such a way as to speed up the reaction.

By reducing the activation energy, enzymes enable chemical reactions to proceed at a faster rate. The lower activation energy allows reactant molecules to reach the transition state more easily, resulting in a quicker conversion of reactants to products.

Therefore, the correct answer is A) The reaction proceeds at a faster rate.
