Conformational change
(Science: cell biology) alteration in the shape usually the tertiary structure of a protein as a result of alteration in the environment ph, temperature, ionic strength) or the binding of a ligand (to a receptor) or binding of substrate (to an enzyme).
Molecules move within the cell or from one cell to another through different strategies. Transport may be in the form of simple diffusion, facilitated diffusion, active transport, osmosis, endocytosis, exocytosis, epithelial transport, or glandular secretion. This tutorial provides elaborate details on each of these mechanisms. Find out how. ..
