Q. No.If for some reason our goblet cells are non-functional, this will adversely affect:
1. production of somatostatin
2. secretion of sebum from the sebaceous glands
3. maturation of sperms
4. smooth movement of food down the intestine
When breast feeding is replaced by less nutritive food low in proteins and calories, infants below the age of one year are likely to suffer from:
1. marasmus
2. rickets
3. kwashiorkor
4. pellagra
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. | Gastric juice will be deficient in chymosin |
| 2. | Gastric juice will be deficient in pepsinogen |
| 3. | In the absence of HCl secretion, inactive pepsinogen is not converted into the active enzyme pepsin |
| 4. | Enterokinase will not be released from the duodenal mucosa and so trypsinogen is not converted to trypsin |
1. Duodenum : Triglycerides Monoglycerides
2. Small intestine : starch Disaccharide (maltose)
3. Small intestine : Proteins Amino acids
4. Stomach : Fats Micelles
