Active transport is against the concentration gradient and is more rapidly than passive transport. Energy is utilized for transport and it is solute specific. Khwaish carries particles are proteins. There are two ways of active transport first one is symport/co-transport and another one is anti transport. Symport is the transport of different substances by the same carrier molecule in the same direction and ant-transport is the transport of two different substances in the opposite direction by the same carrier molecule. Inactive transport, two processes are involved first one is exocytosis and another one is endocytosis. So take Active Transport quiz and increase your knowledge about active transport.
