Hello everyone. Let's look at our next problem here. This says, what kind of receptor do peptide hormones have? Well, let's recall from our content video, what is special about peptide hormones? Well, as we recall they are we can look at their names peptide and that helps us to remember that they are made of small chains of amino acids. Most of the hormones were familiar with our steroid home runs and steroid hormones with their with their ring structure are in general non polar, but amino acids in general are polar molecules. So when we think about hormones that are messengers throughout the body, a non polar molecules such as steroid hormone can cross the cell membrane and enter a cell but a polar molecule cannot cross the membrane. So if we're looking for the location of receptor, a peptide hormone will need a receptor on the surface of the cell. And choice A here indeed is cell surface receptor. Whereas when we look at our other choices, choice B is cytoplasmic receptor internal to the cell in the cytoplasm nuclear receptor and the nucleus also internal to the cell cannot B. Choice C, choice D. All of the above. Well incorrect since B and C. Are incorrect. So, our answer here is choice a cell surface receptor. See you in the next video
