Hey, everyone. Let's take a look at this question together which of the following proteins is found in red blood cells and is responsible for binding and transporting oxygen. Is it answer choice. A Albin answer choice B fibrinogen, answer choice C, hemoglobin or answer choice D gamma globulin. Let's work this problem out together to try, trying to figure out which of the following proteins is found in red blood cells and is responsible for binding and transporting oxygen. So we can recall that when it comes to the red blood cells and binding and transporting oxygen, we note that the binding of the oxygen in the red blood cells is related to the iron that is found in the group of the red blood cell. Since the iron in that heme group helps the oxygen to bind to the red blood cell. And when we're talking about that heme group, we know that the hem group is found within the protein of the red blood cell that is called hemoglobin, which is answer choice c. The correct answer since the red blood cells contain the protein that is called hemoglobin, which contains the hem group and within the hem group, you have an iron atom that undergoes a change in its electronic state allowing oxygen to bind. So answer choice C is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
