Question

Select the correct match of the digested products in humans with their absorption site and mechanism

• A. Glycine, glucose - Small intestine, active
• B. Fructose, $N{a}^{+}$ - Small intestine, Passive absorption
• C. Glycerol, fatty acids - Duodenum, moves as chylomicron
• D. Cholesterol, maltose - Large intestine, active absorption

Answer 1

The correct option is A

Glycine, glucose - Small intestine, active

The small intestine is a major area of absorption of nutrients. Approximately 80% of absorption takes place here. Glucose, fatty acids and amino acids(glycine, etc) are absorbed through mucosa into blood and lymph by active absorption.
The colon absorbs $N{a}^{+}$ more efficiently than the small intestine.
