Reaction temperature
B
Product concentration
C
Activation energy
D
Reaction pressure
Verified step by step guidance1
Understand that enzymes are biological catalysts that speed up chemical reactions without being consumed in the process.
Recognize that catalysts, including enzymes, work by providing an alternative reaction pathway with a lower activation energy.
Activation energy is the minimum energy required for a chemical reaction to occur. Lowering this energy allows more reactant molecules to have enough energy to reach the transition state.
Enzymes do not affect the reaction temperature, product concentration, or reaction pressure directly. Their primary role is to lower the activation energy.
Conclude that the aspect of a chemical reaction that enzymes lower is the activation energy, facilitating a faster reaction rate.
