Detailed explanation-1: -So, the correct answer is ‘They are all proteins except ribozymes.
Detailed explanation-2: -Enzymes are the biological polymers accelerating a biochemical reaction. Initially, enzymes react with molecules known as substrates converting them into distinct molecules known as products. They exist in all fluids and tissues of the body.
Detailed explanation-3: -Answer and Explanation: Of the following regarding enzymes, enzymes being consumed by the reaction they catalyze is incorrect. Enzymes are special in that they’re able to catalyze many different reactions without being consumed or used up by the specific reaction.
Detailed explanation-4: -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.
