Questiоn 1: Anаlyzing Cоncepts: Cоmpаre & Contrаst Cellular Organelles Give an in-depth explanation written in paragraph form for the following questions. Each answer should be at least 3-5 sentences in length and answer all parts of the question completely. The key distinguishing feature separating prokaryotes and eukaryotes is the existence of membrane bound organelles within eukaryotic cells. Each organelle contains its own specialized set of proteins to perform the specific functions of the organelle. Knowing which organelle contains a protein can also give us clues to the function of the protein. Imagine you are studying a novel protein you have creatively named Protinia. You want to determine [where Protinia is normally located within a cell], so you use a procedure called differential centrifugation. As shown in the image below, differential centrifugation allows you to separate organelles based on their size as well as other characteristics. Fig. 1: Tube A shows the mix of all cellular components. The numbers represent ‘spinning’ the sample at different speeds to cause larger particles to ‘pellet’ at the bottom of the tube. The ‘supernatants’ (portion of the solution NOT in the pellet) are then transferred to a new tube and then spun again at a higher speed. Use this figure as well as the following table of information about the organelles to help you answer the questions. Organelle Average Diameter Specific Proteins Present Typical pH Nucleus 7 μm Histones 7.2 Mitochondria 0.7 μm ATP Synthase 8.0 Golgi 100 nm Glycosylase 6.0 Endoplasmic Reticulum 200 nm Glucose-6-Phosphatase 7.2 Lysosome 500 nm Protease 4.0 1B. Explain the connection between the steps of differential centrifugation and the information in the table. What tube(s) from Figure 1 (A,B,C,D, or E) would contain the lysosome? Explain your prediction. 5 pts Copyright 2022 by Edmonds College Department of Biology. All rights reserved. Online sharing or distribution is prohibited.

Gооd Luck Everyоne. I know thаt you hаve been working hаrd and I am confident that you know the material. You will do well. Please help me to find your answers more quickly and be able to comment on your exams while grading. Proper formatting your Uploaded work for the exam or group project Please format your work in the manner described to earn full credit for formatting. Upload your work to the Exam Submission Page as a single pdf file. Please scan in each page of your work and save the file using the name given in the Upload work page for the assignment. Please do not arrange all the pages of work and take "1" picture of the work since I cannot grade the work in this format. Make sure that your work is legible and leave room after each question so that I have room to make comments. Leave 3 lined rows after each question Use the entire width of the page to answer your questions. Do not split the page into columns and write your answers in columns as I do not have any room to comment and I cannot find your answers easily. Please circle your final answer so that it is easily found. Please see below for an example of the format I want.
