Nicolson proposed a new model of the plasma membrane that, compared to earlier understanding, better explained both microscopic observations and the function of the plasma membrane. The proportions of proteins, lipids, and carbohydrates in the plasma membrane vary between different types of cells. These same sites serve as places for antibodies to attach, and either destroy or inhibit the activity of the virus. Like steroid hormones, it can diffuse directly across the plasma membrane thanks to its small size. So, many different kinds of molecules (including large, hydrophilic or "water-loving" ones) may act as ligands. Binding of a ligand to a receptor changes its shape or activity, allowing it to transmit a signal or directly produce a change inside of the cell. This e book exhibits that the identical kinetic.
