Select the correct match of the digested products in humans given in column-I with their' absorption site and mechanism in column-II.
Column I | Column II | |
1. | Fructose, Na+ | Small intestine, passive absorption |
2. | Glycerol, fatty acids | Duodenum, move as chilomicrons |
3. | Cholesterol, maltose | Large intestine, active absorption |
4. | Glycine, glucose | Small intestine, active absorption |
1. (1)
2. (2)
3. (3)
4. (4)
Carrier ions like Na+ facilitate the absorption of substances like:
1. amino acids and glucose
2. glucose and fatty acids
3. fatty acids and glycerol
4. fructose and some amino acids
Which one of the following statement is true regarding digestion and absorption of food in humans?
1. | Oxyntic cells in our stomach secrete the proenzyme pepsinogen |
2. | Fructose and amino acids are absorbed through intestinal mucosa with the help of carrier ions like Na+. |
3. | Chylomicrons are small lipoprotein particles that are transported from intestine into blood capillaries. |
4. | About 60% of starch is hydrolysed by salivary amylase in our mouth. |
1. Duodenum : Triglycerides Monoglycerides
2. Small intestine : starch Disaccharide (maltose)
3. Small intestine : Proteins Amino acids
4. Stomach : Fats Micelles
