Which of the following is responsible for lowering the activation energy of a chemical reaction?Group of answer choicesATPadditional buildup of substrateenzyme activityADP accumulation
Solution
The answer is enzyme activity. Enzymes are biological catalysts that speed up chemical reactions by lowering their activation energy. This means they reduce the amount of energy needed for reactants to reach the transition state, which is the point at which the reaction can proceed. This is done by providing an alternative reaction pathway with a lower activation energy. Therefore, enzyme activity is responsible for lowering the activation energy of a chemical reaction.
