WebCyclic AMP is hydrolyzed by a phosphodiesterase. Perhaps a key point in the modulation system is GTP hydrolysis by the G‐protein. This causes adenylate cyclase to return to the unstimulated state. All signaling … WebThe binding of calcium ions by calmodulin provides the means whereby changes in calcium ion concentration are used to alter cellular activities. Why does calmodulin bound with calcium interact with target proteins but free calmodulin does not? a - Calcium ions serve to bridge negatively charged groups on calmodulin and the target protein.
