Chemically, almost all enzymes are

Correct answer: A. globular proteins

  • A. globular proteins
  • B. lipids
  • C. polysaccharides
  • D. nucleotides

Explanation

An enzyme is a globular protein whose precisely folded tertiary structure creates the active site, which is why anything that unfolds the protein destroys the catalytic power. The globular rather than fibrous form matters because it makes the molecule soluble and compact. The one exception is the small group of catalytic RNA molecules called ribozymes.

About Characteristics of Enzymes

Enzymes are globular biological catalysts that lower activation energy without being consumed, usually showing specificity for particular substrates. Questions cover active sites, enzyme substrate complexes, the lock and key and induced fit models, intracellular and extracellular action, and the effects of denaturation, while distinguishing enzymes from non biological catalysts.
