Question

146) Generally glucose and amino acids are absorbed into blood capillaries by

1) facilitated diffusion 2) active transport

3) simple diffusion 4) exocytosis

​

Answer 1

Answer:

Absorption of Monosaccharides: Absorption of glucose and galactose occur through active transport. Sodium pump on the cell membrane helps in its active transport. Glucose, galactose and fructose are absorbed into the blood capillaries. Galactose is the most rapidly transported monosaccharide.

On the other hand, amino acids and monosaccharides that enter the blood capillary network are carried away by the blood. But, larger molecules from the digestion of fat enter the lacteal. These are then emptied into the lymphatic system, which eventually discharges its contents into the blood system. Through the processes of Osmosis and Diffusion, water and fatty acids are absorbed. The other nutrients such as glucose, amino acids, & minerals are absorbed by active transport.

So the correct option is 'Galactose is the end product of milk protein digestion and is absorbed in small intestine by active process

'.
