The gastric juice of infants contains:
The initial step in the digestion of milk in an infant is carried out by:
1. Lipase | 2. Trypsin |
3. Rennin | 4. Pepsin |
1. | Pancreatic amylase → salivary amylase → lipases |
2. | Disaccharidase like maltase → lipases → nucleases |
3. | Salivary amylase → pancreatic amylase → disaccharidases |
4. | Salivary maltase → carboxy peptidase → trypsinogen |
1. Rennin
2. Lipase
3. Trypsin
4. Pepsin
If for some reason the parietal cells of the gut epithelium become partially non-functional, what is likely to happen:
1. | The pH of the stomach will fall abruptly |
2. | Steapsin will be more effective |
3. | Proteins will not be adequately hydrolysed by pepsin into proteoses and peptones |
4. | The pancreatic enzymes, and especially trypsin and lipase, will not work efficiently |
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 |
