Recetor Proteins
Recognition Proteins
Indentify the type of substances that enter the cell.
Adhesion Proteins
Comunication Proteins
Diffusion
The process by which molecules spread from areas of high concentratiion, to areas of low concentration. When the molecules are even throughout a space
Electric Gradient
Is a spatial variation of both electrical potential and chemical concentration across a membrane.
Pressure Gradient
Is a physical quantity that describes in which direction and at what rate the pressure changes the most rapidly around a particular location.
Osmosis
Is the movement of solvent molecules through a selectively-permeable membrane into a region of higher solute concentration, aiming to equalize the solute concentrations on the two sides.
Hypotonic Solution
Is the same as the solute concentration of another solution with which it is compared.
Hypertonic Solution
Isotonic Solution
Hydrostatic Pressure
Is the pressure exerted by a fluid at equilibrium due to the force of gravity.
Osmotic Pressure
Is the pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.
Endocytosis
Exocytosis
A vesicle moves to the cell surface, and then the protein-studded lipid bilayer of its menbrane.
Phagocytosis
("cell eating")
