A) synthesizing more of the hormone than is actually needed B) increasing the basal metabolic rate in the target organ C) not responding to a feedback mechanism D) binding to specific receptors and employing the services of G proteins and cAMP D.
WebThese second messengers activate other enzymes such as those that phosphorylate or dephosphorylate proteins. Adding a phosphate to an enzyme is like flipping a light switch, sometimes that switch turns off the enzyme (inactive) and sometimes the switch turns on the enzyme (active). Additionally, the second messenger may increase intracellular ...
