(Follicle stimulating hormone) is a glycoprotein that is lipid insoluble and so cannot penetrate target cells. It forms a hormone-receptor complex by binding to particular receptor molecules on the cell membrane's surface. The enzyme adenylate cyclase is released from the receptor site as a result of this combination. From ATP, this enzyme produces cell cyclic adenosine monophosphate (cAMP). The cAMP stimulates the cell's existing enzyme system. The metabolic processes in the cell are accelerated as a result of this. The hormone is referred to as the first messenger, whereas cAMP is referred to as the second messenger. The hormone-receptor complex alters the permeability of the cell membrane to allow items to pass across it more easily. As the cell obtains the required ingredients, its actions grow.
