Verified step by step guidance1
Understand that enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to proceed.
Recognize that the transition state is a high-energy, unstable state that reactants must pass through to be converted into products.
Enzymes stabilize the transition state, which reduces the activation energy needed for the reaction, making it easier for the reaction to occur.
The transition state has the highest free energy compared to the reactants and products, which is why enzymes are designed to bind to it specifically.
By binding to the transition state, enzymes lower the energy barrier, facilitating the conversion of reactants to products more efficiently.
