During the hormone action through membrane receptors, the peptide hormones bind to specific receptor molecules to form a complex and release an enzyme _____.
Options:
Answer:
A
Solution:
Peptide hormones are water-soluble and cannot cross the lipid bilayer of the target cell membrane.
They interact with specific membrane-bound receptors on the surface of the target cell to form a hormone-receptor complex.
The formation of this complex induces a conformational change that activates nearby G-proteins, which in turn activate the membrane-bound enzyme adenylate cyclase.
Adenylate cyclase catalyzes the conversion of ATP into cyclic AMP (cAMP), which acts as a second messenger to trigger a cascade of biochemical responses within the cell.
Answer: adenylate cyclase
