Where does the major portion of the chemical digestion of lipids occur?
- A. Mouth.
- B. Stomach.
- C. Small intestine.
- D. Large intestine.
Correct Answer: C
Rationale: The correct answer is C: Small intestine. The majority of lipid digestion occurs in the small intestine, where bile and pancreatic lipase are active. Lipids are broken down into fatty acids and glycerol in the small intestine. Choices A, B, and D are incorrect because the mouth and stomach play minor roles in lipid digestion, and the large intestine is mainly responsible for absorbing water and electrolytes from the indigestible food residues.
