The biomolecular interaction between protein receptors and ligands is similar to that of en- zymes and substrates, which depends in part on the shape of the protein. The shape of a protein, in turn, depends on the presence of appropriate chemical bonds in the protein. Many common medications function by altering the interactions between protein receptors and ligands, thereby interfering with the normal response of a cell to specific signals. Which of the following best describes a mechanism by which a drug might interfere with a normal cellular response? A A medication interrupts the electron transport chain in a cell and makes it unable to syn- thesize sufficient ATP. B с D A medication causes the cell to become more permeable and unable to maintain the conditions that allow a normal response. A medication enters the nucleus of a cell and alters the nucleic sequence for a specific receptor protein. A medication enters a target cell and acts as an inhibitor to an intercellular protein receptor.
