Question

Choose the correct answer from the alternatives given.
Which of the following accurately represents the sequence of components in a cellular response to a peptide hormone

• A. Hormone binding to adenylate cyclase-Gproteinprotein kinasephosphorylation of enzymes
• B. Hormone binding to receptorG proteincAMP produced from GTPprotein kinase
• C. Hormone binding to cAMPG protein cAMP dependent protein kinaseadenylate cyclase
• D. Hormone binding to receptorG proteinadenylate cyclaseprotein kinase

Answer 1

The correct option is B Hormone binding to receptorG proteincAMP produced from GTPprotein kinase

The hormone-receptor complex in the nucleus binds to a DNA sequence called hormone response element which triggers transcription and translation. The corresponding protein product can then meditate in cell function. So, the correct option is "hormone binding to receptorG proteincAMP produced from GTPprotein kinase".
