WebJun 19, 2024 · Symport and antiport are the two types of secondary active transport. In symport , both driving and driven molecules are transported in the same direction. The Na + /glucose cotransporter (SGLT1) is an example for symports in which both sodium and glucose are transported into the cell.

WebAnd then another example of secondary active transport is an antiporter, or an exchanger. In the symporter, a cotransporter, they're both going in the same direction even though one is going with its concentration gradient, that's essentially powering it, and the other one is … Here, the cell can't import glucose for free using diffusion, because the natural … So this is a high concentration and that's a low concentration.

Erythrocyte glucose transporter is an example of … WebMar 29, 2024 · The main difference between Uniport, Symport, and Antiport is that Uniport moves molecules across the membrane independently of other molecules, and Symport moves two types of molecules in the same direction, but Antiport moves two types of molecules in opposite directions. In addition, all channel proteins are examples of …
WebA symport would function as an antiport if its orientation in the membrane were reversed (i.e., if the portion of the molecule normally exposed to the cytosol faced the outside of the cell instead). G. The membrane potential of an axon temporarily becomes more negative when an action potential excites it.
