When transport proteins simultaneously move two molecules across a membrane in the same direction ,the process is called

Options

A. uniport
B. antiport
C. symport
D. diffusive port.

Answer

C

Explanation

Some carries proteins allow transport only if two types of molecules move together. This is called co-transport. It is of two type: symport and antiport method. In symport method of co-transport, both molecules cross the membrane in the same direction at the same time. In antiport method of co-transport, both molecules move in opposite direction. When a molecules moves across a membrane independent of other molecule, the process is called uniport.
