STOP! Please read this question CAREFULLY before answering. You are not telling me what you *wish* we’d gone over in class; you are explaining something you learned (in detail!). This is a “choose your own question” question! Please think about any single topic from these chapters that you wish: this can be something you studied for that wasn’t on this test, or something you found especially interesting, or anything else you want from this content. Name the topic and explain it fully here. Write at least a full paragraph (minimum 4-5 sentences; no bullet points), although you may go longer. This is your chance to demonstrate good knowledge of a single topic from these chapters. Please do not just list names of multiple topics, or just tell me you found [name of topic] to be really interesting. You may tell me [name of topic] was really interesting, but you must demonstrate to me that you learned about and understand the topic by explaining to me how it works! Relax, and please don’t stress – this is your chance to choose your own topic/question and show me you learned something from this course by telling me about it – i.e., this is meant to be a very gentle last question on this test! 🙂 Copyright 2024 by Edmonds College Department of Biology.

(OPTIONAL) Up to 2 points of extra credit – Numerous researchers around the world worked to develop vaccines to SARS-CoV-2, the novel coronavirus causing the pandemic impacting all of our lives. Although there are different approaches taken, the basic idea is for the vaccine to get our adaptive immune system to produce antibodies (note: there is more to the story, but we won’t worry about that for now). Imagine an individual is given the vaccine, responds well, and produces antibodies. How would these antibodies protect that individual from getting sick from the novel coronavirus? I.e., what is the core simple function or property of antibodies that allows them to be protective? Briefly explain – it should be possible to correctly answer this question in just a correct sentence or two based on what you have already learned in BIOL& 211. Hint: you studied experiments in Chapter 11 in which scientists used antibodies to study proteins involved in cell-cell adhesion. What did the antibodies do in these experiments?

A white blood cell of your immune system uses phagocytosis to capture and engulf a bacterial pathogen. Once inside the cell, the vesicle (called a phagosome) containing the bacterium is fused with a ______, an organelle that contains digestive enzymes that help break apart the pathogen.
