Detailed explanation-1: -Enzymes are biological catalysts which speed up biochemical reactions. According to the most widely accepted theory, enzymes bind to the substrate molecule and form a transition state. During the progress of a reaction the substrates are separated from products by an energy barrier which the substrates need to cross.
Detailed explanation-2: -This statement about enzymes is true: Enzymes accelerate reactions by lowering the activation energy. Enzymes are proteins whose three-dimensional form is key to their function. Enzymes do not alter the overall change in free energy for a reaction.
Detailed explanation-3: -So, the correct answer is ‘Enzymes are used up in reactions’.
Detailed explanation-4: -Which of the following statements about enzyme function is true?-Enzymes increase the rate of chemical reactions by lowering activation energy barriers.
