ncert.nic.in11.1.4 Comparison of Different Transport Processes Table 11.1 gives a comparison of the different transport mechanisms. Proteins in the membrane are responsible for facilitated diffusion and active transport and hence show common characterstics of being highly selective; they are liable to saturate, respond to inhibitors and are under

www.sd27j.orgActive Transport Across the Cell Membrane Active transport is the movement of solutes against a gradient and requires the expenditure of energy, usually in the form of ATP. Active transport is achieved through one of these two mechanisms: Protein Pumps • Transport proteins in the plasma membrane transfer solutes such as small ions (Na+, K+ ...
