Insulin receptor normally exists as preformed, constitutive dimer. Group of answer choicesTrueFalse

Insulin uses which second messenger? Group of answer choices Insulin does not use second messengers as its receptors have their own enzymatic activity cAMP InP3 DAG calcium

Which one of the following statements is INCORRECT? Question 16Select one:a.Insulin stimulates the production of glycogen synthase enzyme, which favours glycogenesis in hepatocytes.b.Peptidase enzymes in the enterocyte cytoplasm degrade absorbed peptides into amino acids.c.Lipid storage ceases during fasting because there are minimal levels of insulin in the blood to synthesise lipoprotein lipase enzymed.The insulin receptor is a tyrosine kinase receptor that is comprised of 4 subunits: 2 membrane-spanning alpha subunits, and 2 insulin-binding beta subunits.e.Glucose enters the liver via the GLUT2 transporter, which is active regardless of the presence of insulin.
