Verified step by step guidance1
Understand the role of enzymes in catalysis: Enzymes are biological catalysts that speed up chemical reactions without being consumed in the process.
Recognize the concept of activation energy: Activation energy is the minimum energy required for a chemical reaction to occur. It is the energy barrier that reactants must overcome to transform into products.
Identify how enzymes affect activation energy: Enzymes lower the activation energy of a reaction, making it easier for the reaction to proceed at a faster rate.
Clarify the misconception about equilibrium: Enzymes do not change the equilibrium position of a reaction; they only speed up the rate at which equilibrium is reached.
Explain why enzymes do not provide energy: Enzymes do not supply energy to the reaction; they facilitate the reaction by providing an alternative pathway with a lower activation energy.
