Many common medications function by interrupting the normal operation of certain signal transduction pathways. Which of the following describes a possible mechanism by which a certain medication may interrupt a signal transduction pathway? A A medication enters the target cell and triggers apoptosis by causing the release of di- gestive enzymes from cell lysosomes. B A medication interacts with the phospholipid bi-layer of the cell membrane and in- creases its permeability. C A medication binds to membrane-bound glucose proteins and acts as an allosteric in- hibitor that prevents the intake of glucose by the cell. D A medication diffuses through the membrane of a target cell and inhibits an enzyme that normally synthesizes a second messenger.
