Which digestive organ digests food using acids and enzymes?

• A. Pancreas
• B. Esophagus
• C. Liver
• D. Stomach

Answer: (D)

Digestion using acids and enzymes happens most prominently in the stomach. The stomach lining releases gastric juice that contains hydrochloric acid, which creates a highly acidic environment, and the enzyme pepsin, which begins breaking down proteins. This combination—acid to unfold proteins and activate enzymes, plus a protease enzyme kicking off protein digestion—lets the stomach start processing food efficiently. The pancreas is a crucial player in digestion too, producing enzymes like amylase, lipase, and proteases, but these are released into the small intestine rather than acting inside the stomach, and bicarbonate is also released to neutralize the acid there. The esophagus mainly moves food toward the stomach through peristaltic contractions and doesn’t perform chemical digestion with acids or enzymes. The liver produces bile that assists fat digestion but isn’t an enzyme and doesn’t digest food by itself. So, the organ that digests food using acids and enzymes is the stomach.
