Active transport
Explanation:
The process of the plasma membrane pumping excess sodium out of a cell into an environment where there is a lower concentration of sodium is called active transport
- Active transport drives the transportation of solute against the concentration gradient across the membrane
- It includes two types of transport: primary active transport and secondary active transport
- Transport of sodium occurs through primary active transport
- Primary active transport catalyzes direct hydrolysis of ATP during solute transportation called ATPase
