Verified step by step guidance

Understand the role of the pancreas in digestion: The pancreas is an organ that plays a crucial role in both the digestive and endocrine systems. It produces enzymes and hormones that aid in digestion and regulate blood sugar levels.

Identify the substances produced by the pancreas: The pancreas produces several important substances, including digestive enzymes like amylase, hormones like insulin and glucagon, and bicarbonate ions.

Recognize the function of bicarbonate: Bicarbonate is an alkaline substance produced by the pancreas. Its primary role in digestion is to neutralize the acidic chyme that enters the small intestine from the stomach, creating a more suitable pH environment for digestive enzymes to function.

Differentiate between the options: Amylase is an enzyme that breaks down carbohydrates, glucagon is a hormone that raises blood sugar levels, and insulin is a hormone that lowers blood sugar levels. None of these directly neutralize stomach acid.

Conclude that bicarbonate is the correct answer: Based on the functions of the substances produced by the pancreas, bicarbonate is the one specifically responsible for neutralizing stomach acid.
