Verified step by step guidance1
Understand the role of enzymes: Enzymes are biological catalysts that speed up chemical reactions in living organisms.
Identify the concept of activation energy: Activation energy is the minimum energy required for a chemical reaction to occur.
Recognize how enzymes affect activation energy: Enzymes lower the activation energy, making it easier for the reaction to proceed.
Clarify the effect on reaction rate: By lowering the activation energy, enzymes increase the rate of the chemical reaction.
Eliminate incorrect options: Enzymes do not increase activation energy or temperature; they specifically lower activation energy to increase reaction rates.
