BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Answer and Explanation: The given statement is false. The enzyme contains the structure of the protein.

Detailed explanation-2: -Enzymes lower the activation energy of the reaction but do not change the free energy of the reaction. A substance that helps a chemical reaction to occur is called a catalyst, and the molecules that catalyze biochemical reactions are called enzymes.

Detailed explanation-3: -The correct answer: The statement that is false about the enzymes d. A specific enzyme can catalyze a variety of chemical reactions. The enzymes are basically proteins that are produced from the secretory cells.

Detailed explanation-4: -Do enzymes provide energy? Although enzymes help to lower this activation energy, allowing reactions to occur more quickly, enzymes do not change or add to the overall energy of a reaction.

Detailed explanation-5: -Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction.
