Questions: Which glands will produce enzymes that can digest all the major organic macromolecules, including carbohydrates, lipids, proteins, and nucleic acids? Cecum Mouth Pancreas Stomach Liver

The answer is the third one: Pancreas.

Explanation for each option:

1. Cecum: The cecum is a part of the large intestine and does not produce digestive enzymes. It primarily plays a role in absorbing fluids and salts that remain after intestinal digestion and absorption.

2. Mouth: The mouth contains salivary glands that produce enzymes like amylase, which begins the digestion of carbohydrates. However, it does not produce enzymes that digest lipids, proteins, or nucleic acids.

3. Pancreas: The pancreas is the correct answer because it produces a wide range of digestive enzymes, including amylase for carbohydrates, lipase for lipids, proteases like trypsin and chymotrypsin for proteins, and nucleases for nucleic acids. These enzymes are secreted into the small intestine, where they help digest all major types of organic macromolecules.

4. Stomach: The stomach primarily produces pepsin, an enzyme that digests proteins. It does not produce enzymes for digesting carbohydrates, lipids, or nucleic acids.

5. Liver: The liver produces bile, which aids in the digestion and absorption of lipids, but it does not produce digestive enzymes for carbohydrates, proteins, or nucleic acids.

In summary, the pancreas is the gland that produces enzymes capable of digesting all major organic macromolecules.
