In the hormonal activation of adenylate cyclase and the subs

In the hormonal activation of adenylate cyclase, and the subsequent formation of cyclic AMP, which of the following components is NOT necessary? Question 23 options: A. hormone receptor B. GTP C. ATP D. GDP E. guanyl nucleotide regulatory protein

Solution

G protein or Guanyl nucleotide regulatory protein , it act as a molecular switch inside a cell. their activity is regulated by factors that help them to bind and hydrolyze GTP TO GDP. G protein\'s alpha subunit starts cAMP pathway.

so in the hormonal activation of adenylate cylase, and the subsequent formation of cAMP the component that is unnecessary is GDP.
