transport proteins allow the movement of ions and small molecules across plasma membranes. identify the type of transport protein from each example as uniporter, symporter, or antiporter.



Answer :

Transport proteins allow the movement of ions and small molecules across plasma membranes. The type depends on the molecules that need to be moved. Uniporters are used to move only one type of molecule, symporters are used to move two molecules in the same direction, and antiporters are used to move two molecules in opposite directions.

Transport proteins are proteins that facilitate the movement of ions and small molecules across a plasma membrane. These proteins help to maintain the balance of ions and molecules within the cell and are responsible for the regulation of the cell’s environment. Transport proteins come in three types: uniporter, symporter, and antiporter. Each type of transport protein works differently to move ions and molecules across the membrane.

A uniporter is a type of transport protein that facilitates the movement of only one type of molecule across a membrane. An example of a uniporter is the sodium-potassium pump, which pumps sodium out of the cell and potassium into the cell.

A symporter is a type of transport protein that moves two molecules in the same direction across a membrane. An example of a symporter is the glucose-sodium symporter, which moves glucose and sodium into the cell at the same time.

An antiporter is a type of transport protein that moves two molecules in opposite directions across a membrane. An example of an antiporter is the sodium-calcium exchanger, which moves sodium out of the cell and calcium into the cell.
