Mineral ion like sodium is absorbed in the intestine mainly by ---------------.
- AOsmosis
- Correct answerBActive transport
- CSimple diffusion
- DPassive transport
Solution
Absorption of substances in the intestine occurs by simple diffusion, facilitated transport, or active transport.
Active transport occurs against the concentration gradient and hence requires energy in the form of ATP.
Various nutrients like amino acids, monosaccharides like glucose, and electrolytes like $Na^{+}$ are absorbed into the blood by active transport.
Answer: Active transport
