During signal transduction (a) the cell converts an extracellular signal into an intracellular signal that leads to a change in some cell process (b) a signaling molecule directly activates or represses several genes (c) each enzyme catalyzes production of one molecule of product (d) enzymes in the signal cascade remain active until the last component of the pathway alters a cellular process (e) the signal is terminated by cyclic AMP
signal transduction pathways involving phosphorylation of a series of proteins is generally associated with which of the following events? a. production of cAMP in the process of signal transduction b. structure changes to each protein in the series, leading to changes in function c. release of Ca 2+ into the cytosol d. activation of a ligand-gated ion channel e. binding of a hormone to an intracellular receptor
