Verified step by step guidance

Understand the role of enzymes in biochemical reactions: Enzymes are biological catalysts that speed up chemical reactions without being consumed in the process.

Recall the concept of activation energy: Activation energy is the minimum energy required for reactants to transform into products during a chemical reaction.

Learn how enzymes affect activation energy: Enzymes lower the activation energy by stabilizing the transition state, making it easier for the reaction to proceed.

Clarify that enzymes do not supply energy or permanently alter products: Enzymes facilitate the reaction but do not provide energy or change the chemical nature of the products.

Understand that enzymes do not affect the equilibrium constant: Enzymes speed up the rate at which equilibrium is reached but do not change the equilibrium constant itself.
