What are catalysts that break down complex food molecules?

• A. Enzymes
• B. Hormones
• C. Minerals
• D. Vitamins

Answer: (A)

Enzymes are the catalysts that drive digestion. They speed up the chemical breakdown of large, complex food molecules into smaller, absorbable units. Each enzyme targets a specific substrate—for example, amylase splits starch, proteases break down proteins, and lipases digest fats. They’re produced by the digestive system and work under the body’s conditions by lowering the activation energy needed for reactions, allowing digestion to occur efficiently at body temperature and within the varying pH environments of the mouth, stomach, and intestines. Hormones regulate the process but don’t catalyze the breakdown themselves. Minerals and vitamins aren’t catalysts; they often serve as cofactors or coenzymes that support enzyme activity. So, enzymes are the catalysts that break down complex food molecules.
