Which statement is true regarding the pancreas?

A. Pancreatic juice is rich in the enzyme amylase that breaks down carbohydrates.
B. Pancreatic juice is rich in the enzyme lipase that breaks down fats.
C. Pancreatic juice is rich in the enzyme trypsin that breaks down proteins.
D. The pancreas secretes sodium bicarbonate.

Answer :

Final answer:

The pancreas produces a juice rich in the enzyme amylase which breaks down carbohydrates. Lipase and trypsin, also produced by the pancreas, break down fats and proteins, not carbohydrates. The pancreas also secretes sodium bicarbonate, an alkaline substance that neutralizes the acidic chyme from the stomach.

Explanation:

The pancreas plays a crucial role in the digestive system. It is true that pancreatic juice is rich in several important enzymes. One of these is the enzyme amylase, which aids in the breakdown of carbohydrates. This is why amylase is often associated with the digestion of carbs. Hence, the statement 'pancreatic juice is rich in the enzyme amylase that breaks down' is correct.

However, it's not accurate to say that lipase or trypsin, other enzymes produced by the pancreas, are responsible for breaking down carbohydrates. Rather, lipase helps break down fat, while trypsin primarily breaks down proteins into their smaller building blocks.

Lastly, it is indeed true that the pancreas secretes sodium bicarbonate. This bicarbonate-rich pancreatic juice serves to neutralize the acidic chyme, hence providing an optimal environment for enzymatic activity.
