aqa a level biology digestion and absorption
| Front | how do microvilli increase the rate of co transport |
| Back | microvilli on the epithelial cell increase surface area so more co transport proteins can fit within the membrane |
| Front | Where does lipid digestion begin |
| Back | duodenum |
| Front | Why do fatty acids and monoglycerides not require co transport, |
| Back | - fatty acids and monoglycerides = non polar, so can easily diffuse across membrane of the small intestine epithelial cells via simple diffusion |
