Identify the correct statement regarding the properties of enzymes.

Options

  1. AEnzymes increase the activation energy of biochemical processes to accelerate them.
  2. BEnzymes are primarily composed of complex polysaccharides.
  3. CEnzymes act as biocatalysts and are required only in very small quantities.
  4. DA single enzyme can efficiently catalyze many unrelated biochemical reactions.

Correct answer

C. Enzymes act as biocatalysts and are required only in very small quantities.

Step-by-step solution

Enzymes are biocatalysts that are required in very small quantities to catalyze biochemical reactions. The other statements are incorrect because: - Enzymes lower (not increase) the activation energy of biochemical processes. - Almost all enzymes are globular proteins, not polysaccharides. - Enzymes are highly specific; a particular enzyme generally catalyzes only one specific reaction or acts on a specific substrate. Answer: Enzymes act as biocatalysts and are required only in very small quantities.
