BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The energy required to reach the transition state (the activation energy) constitutes a barrier to the progress of the reaction, limiting the rate of the reaction. Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction.

Detailed explanation-2: -Enzymes let chemical reactions in the body happen millions of times faster than without the enzyme.

Detailed explanation-3: -Enzymes control the chemical reactions that sustain life. Conditions inside the body must enable enzymes to catalyse the multitude of chemical reactions needed for life processes.

Detailed explanation-4: -Expert-Verified Answer The statement (A) An enzyme functions to increase the activation energy in a reaction is true about enzyme.

Detailed explanation-5: -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.
