Question

What are the different types of transport across cell membranes?

Answer 1

Cell membrane transport:

1. Cell membrane transport refers to the accumulation of mechanisms that control the passage of ions and small molecules through a phospholipid bilayer containing proteins embedded in it.

The different types of transport across cell membranes are as follows:

1. Active transport: Active transport involves the movement of molecules from a region of low concentration to a region with a high concentration against a barrier with the use of gradient or external energy.
2. Passive transport: Passive transport is defined as the movement of solutes from one region of the cell membrane with a high electrochemical potential to the region of lower electrochemical potential on the opposite side.
