For example, how testosterone makes your larynx grow to change your voice and makes you store fat in a masculine distribution among other things, but how exactly does it “tell” the body to do those things? And same with the effects of estrogen.
In: Biology
Hormones cause changes in target cells by binding to specific hormone receptors in the cells. Some cells will only have certain receptors and the quantity of receptors can change as well (like a key and lock). Some hormones can enter the cell and bind to DNA to regulate gene transcription. They basically change the way the cell reads its instructions to make the cells do different things. Some hormones bind to receptors on the outside and trigger signaling pathways that change the production of various cell products that affect the cell in the short-term.
