Insulin acts by which pathway-
ATyrosine kinase
BIntrinsic ion channel
CJAK-STAT-Kinase
DTranscription factor
Which of the following hormones does not mediate its action through cAMP?
AGlucagon
BFollicle stimulating hormone
CEstrogen
DLuteinizing hormone
Which of the following statements best describes the mechanism of action of insulin on target cells?
AInsulin binds to a receptor on the outer surface of the plasma membrane, activating adenylate cyclase through the Gs protein.
BInsulin binds to a cytoplasmic receptor and is transferred as a hormone receptor complex to the nucleus to modulate gene expression.
CInsulin enters the cell and causes the release of calcium ions from intracellular stores.
DInsulin binds to a transmembrane receptor on the outer surface of the plasma membrane, activating the tyrosine kinase in the cytosolic domain of the receptor.
