Question

Why is the observation that one hormone may bind to more than one type of receptor important?

Accepted Answer

Hey everyone. Let's take a look at this question together. Epinephrine increases blood flow to muscles but decreases blood flow to the digestive system, which of the following is responsible for this diverse effect. So let's talk about what we know about hormones and how they function. So we know that epinephrine is a hormone and that hormones bind two receptors on different tissues. And so when the hormone binds to those receptors they have some sort of effect. And so because they have to bind to specific receptors in specific tissues in the muscles, they could have that positive increase. But in the digestive system they get that decrease because they have different tissues that they're binding to and so on. These different tissues are different receptors and these different receptors have different outcomes. For example the increase or the decrease of blood flow in different parts of the body. And so the correct answer here. Answer choice A Because different receptors in different tissues lead to different effects for epinephrine. So, answer choice A is the correct answer. I hope you found this video helpful. Thank you and goodbye.
