- Biology - B5 - Digestion
- The Human Digestive System.
- Enzyme = amylase, substrate = starch, products of digestion = glucose, parts of the gut where the enzyme is found = mouth & small intestine.
- Digestive enzymes.
- Enzyme = carbohydrase, substrate = carbohydrates, products of digestion = glucose, parts of gut where it is found = salivary glands & small intestine
- Digestive enzymes.
- Bile emulsifies fats - breaks it into smaller droplets. This gives enzymes (lipase) a larger surface area to work on.
- Adaptations of the small intestine.
- Very long.
- Large surface area because it's lining is folded & has finger-like projections called villi.
- Cells covering each villus have microvilli, which increase the surface area even more.
- Lining is thin & it has a good blood supply.
