Quizplus · Accepted Answer

Enzymes function as catalysts that speed up chemical reactions in the body. In the digestive tract, enzymes break down complex food molecules into simpler and more easily absorbable forms. Specifically, they break specific chemical bonds in carbohydrates, proteins, and fats, facilitating their digestion and absorption.

Option A is incorrect because enzymes do not create chemical bonds; rather, they break or modify existing bonds. Option B is incorrect because fatty acids and glycerol are already present in small droplets called micelles before they are acted upon by enzymes. Option D is incorrect because enzymes are not involved in neutralizing stomach acids; instead, bicarbonate ions and mucus secreted by the intestine and pancreas play this role.
