Insulin signalling acts through an insulin receptor, which is a receptor tyrosine kinase (TRUE OR FALSE?)
Insulin signalling acts through an insulin receptor, which is a receptor tyrosine kinase (TRUE OR FALSE?)
Homework Answers
Answer : The given statement with respect to insulin receptor is TRUE. Binding of insulin to its receptor which has a tyrosine kinase activates phosphorylates many proteins on their tyrosine residues activating them which in turn leads to such physiological changes such as stimulating the uptake of glucose by liver, skeletal muscle and fat tissue and by inhibiting glycogenolysis and gluconeogenesis.
Insulin is a peptide hormone produced by the beta-cells of the islets of Langerhans in response to elevated blood glucose level. Insulin is a hypoglycemic hormone that lowers blood glucose level through various means.

Choose one out of paracrine signalling, endocrine signalling, autocrine signalling and direct signalling and describe briefly the process by which this occurs. Pick a representative signal molecule from the pathway you have chosen and indicate its function, the type of cell in which it is made and the specific manner in which it acts as a signalling molecule, including the receptor that it binds to. For example if you chose the endocrine signalling pathway you could consider looking at a...
