Webb17 sep. 2024 · The process of active transport takes place in humans during digestion of food in the ileum (small intestine). Once food has been absorbed by the villi after some time the concentration of food molecules inside the villi increases at this point no more food can diffuse in. What are examples of active and passive transport? WebbSecondary Active Transport. Like primary active transport, secondary active transport also moves solutes against their concentration gradients. However, with secondary active transport, ATP is not directly involved in the pumping of the solute. Instead, this process uses the energy stored in concentration gradients to move the solute.
