Verified step by step guidance
1
Understand the role of enzymes: Enzymes are biological catalysts that speed up chemical reactions without being consumed in the process.
Identify the concept of activation energy: Activation energy is the minimum energy required for a chemical reaction to occur. Enzymes work by lowering this energy barrier.
Explore how enzymes affect activation energy: Enzymes decrease the activation energy, making it easier for reactants to convert into products, thus increasing the reaction 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.
Recognize the energy aspect: Enzymes do not provide energy for the reaction; they facilitate the reaction by lowering the activation energy required.
