Cell membrane provides structure for the cell, protects cytosolic contents from the environment, and allows cells to act as specialized units.The two types of transport are Active and passive transport.
Active and passive transport are biological processes that move oxygen, water and nutrients into cells and remove waste products. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand, passive transport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy.
Active Transport :It uses ATP to pump molecules AGAINST/UP the concentration gradient. Transport occurs from a low concentration of solute to high concentration of solute. Requires cellular energy.
Passive transport :Movement of molecules DOWN the concentration gradient. It goes from high to low concentration, in order to maintain equilibrium in the cells. Does not require cellular energy.
