BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Enzymes let chemical reactions in the body happen millions of times faster than without the enzyme. Because enzymes are not part of the product, they can be reused again and again.

Detailed explanation-2: -Enzymes: An enzyme is a chemical that speeds up a chemical reaction without getting used up in the process. Since the enzyme does not get consumed in the process they can be reused.

Detailed explanation-3: -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-4: -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.
