Answer 3

Pancreatic juice: alkaline
- bile: no enzyme, acid chyme to neutralised chyme
- carbohydrase amylase: starch to maltose
- lipase: fats to glycerol+ff acids
- trypsinogen changed to trypsin: proteins to polypeptides

Question 4

Answer 4

Succus entericus: alkaline
- Erepsin: polypeptides to amino acids
- Sucrase: sucrose to g + f
- Maltase: maltose to g+g
- Enterokinase: inactive trypsinogen to active trypsin
- Lipase: fats to ff acids and glycerol
- Lactose: lactose to g+g
