|
Term
|
Definition
| Protein pore through membrane that mediates a high rate of solute transfer/diffusion. Driven by electrochemical gradient. |
|
|
Term
|
Definition
| Intrinsic protein that binds the transported solute & undergoes a conformational change that moves solutes to the other side of the membrane. Slower than channels. |
|
|
Term
|
Definition
| Driven by transported solute's concentration. |
|
|
Term
|
Definition
| Driven by ATPase activity. |
|
|
Term
| Symport or cotransport (secondary active transport) |
|
Definition
| Gradient of one transported solute drives the transport of other solutes in the same direction. |
|
|
Term
| Antiport or countertransport |
|
Definition
| Gradient of one transported substance drives the transport of another in the opposite direction. |
