1. Lipase | 2. Trypsin |
3. Rennin | 4. Pepsin |
Anxiety and eating spicy food together in an otherwise normal human, may lead to:

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

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

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 |
