Question

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 hormone such as insulin.) You would describe the cells from which insulin is secreted and state the overall role of insulin in the body. In signalling pathways, each signal molecule has a receptor that it binds to, so you would indicate what the receptor for insulin is called and what immediate outcome the binding of insulin has to that receptor i.e. in the case of insulin, which regulates glucose uptake in the body, does the receptor directly interact with glucose or is it just part of a much larger signaling cascade.

Answer 1

Endocrine Signalling! It occurs when endocrine colls releases hormones which act on distant target colle. Representative signal molecules (FSH) follicle stimulating harmoone secretes from cells in the anterior pituitary Called gonadotrops and acts on gonads.
