Hi everyone. Let's take a look at this question together determine which of the following labels represents the antigen binding site in the given image. And here we have an image on the screen with several parts that are labeled, that we have to determine which label represents the antigen binding site. So in order to solve this question, we have to recall what we have learned about what the image is depicting to determine which of the following labels on the given image on the screen represents the antigen binding site. And we know that the following labeled structures of the given image include the label letter A represents the F C region. The label of letter B represents the variable antigen binding sites. The variable of letter C represents the light chain and the variable of letter D represents the heavy chains. So since we are looking for the label that represents the antigen binding site, we know that the label represented as letter B are the variable antigen binding sites which we can see on the image on the screen. The antigen binding sites are represented as letter B. So answer choice B is the correct answer and all other answer choices are labels that represent different structures. I hope you found this video to be helpful. Thank you and goodbye.
