Vedclass · Answer

(B) Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy $(E_a)$ required for the reaction to proceed.By providing an alternative reaction pathway with a lower energy transition state,enzymes allow a greater number of substrate molecules to reach the energy threshold at a given temperature,thereby increasing the rate of the reaction.
