The role of adenylate cyclase is:
  • a)
    To degrade steroid hormones, terminating their function
  • b)
    To activate G protein-coupled receptors via phosphorylation
  • c)
    To aid in signal amplification via conversion of GTP to GDP
  • d)
    To cyclize ATP in order to generate second messengers
Correct answer is option 'D'. Can you explain this answer?

Adenylate cyclase is an enzyme that plays a crucial role in signal transduction pathways, particularly those mediated by G protein-coupled receptors (GPCRs). When a hormone or neurotransmitter binds to a GPCR, it activates a G protein, which in turn activates adenylate cyclase.
Activated adenylate cyclase catalyzes the conversion of adenosine triphosphate (ATP) to cyclic adenosine monophosphate (cAMP) by cyclizing the phosphate groups. cAMP acts as a second messenger that can relay the signal from the hormone or neurotransmitter to the intracellular components of the cell.
