the final product of carbohydrate digestion is a:

polysaccharide.
fatty acid.

Explanation:

Question 4

To solve this, we analyze each option:

• Gastric inhibitory peptide (GIP) mainly stimulates insulin release and inhibits gastric acid, not muscle directly to slow food to duodenum.
• Enterogastrone is a hormone that inhibits gastric muscle activity, slowing the passage of food (chyme) into the duodenum.
• Chyme is the semi - digested food in the stomach, not a hormone.
• Cholecystokinin (CCK) stimulates gallbladder contraction and pancreatic enzyme release, not gastric muscle inhibition for slowing food to duodenum.

We evaluate each option:

• The stomach is mainly for digestion (mechanical and chemical) and has limited absorption (e.g., some water, alcohol).
• The small intestine (duodenum, jejunum, ileum) has a large surface area (due to villi and microvilli) and is the major site for absorbing end products of digestion (like monosaccharides, amino acids, fatty acids).
• The cecum is the start of the large intestine and mainly absorbs water and electrolytes, not end products of digestion.
• The large intestine absorbs water, electrolytes, and some vitamins, not the main site for end - product digestion absorption.

We analyze the options:

• Disaccharides are broken down during digestion, they are not the final product.
• Carbohydrates are digested from polysaccharides to disaccharides and then to monosaccharides (e.g., glucose, fructose, galactose). Monosaccharides are the final absorbable products of carbohydrate digestion.
• Polysaccharides are the initial complex carbohydrates (e.g., starch), which are broken down during digestion.
• Fatty acids are the end product of fat digestion, not carbohydrate digestion.

Answer:

B. enterogastrone.
