What will happen if HCl secretion of parietal cells of gastric glands is blocked with an inhibitor?
| 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 |
