A&P I Study Objectives The Cell: Chapter Three Study Objectives 1 Draw a typical eukaryotic animal cell with all the possible organelles; label each organelle and describe its function. Use pg.63, 94-95 2 Describe the chemical composition and arrangement of the cell membrane. 3 Discuss the positions and roles of the cell membrane proteins (both integral and external and internal peripheral). 4 Define and compare tight junctions, desmosomes, and gap junctions. Describe their importance in the functioning of the cell. 5 Differentiate between passive and active membrane transport mechanisms. 6 Relate cell membrane structure to active and passive transport. 7 Define each sub-type of passive transport and cite examples of the use of each of these transport mechanisms. 8 Define each sub-type of active transport and cite examples of the use of each of these transport mechanisms. 9 Explain the terms: diffusion, osmosis, hypertonic, hypotonic, isotonic. 10 Describe the importance of these terms in fluid and electrolyte balance in homeostasis. Be able to predict the movement of solutes and water given concentrations inside and outside the cell. ** Note : Info on objectives # 11-16 on cell respiration can be found in pages 924- 932 of chapter 24 of your textbook. 11 List the four main stages of cell respiration. List the reactants and products as well as the cellular location of each phase. 12 Contrast the two methods of ATP production in cell respiration: substrate –level phosphorylation vs. oxidative level phosphorylation. 13 Be able to identify where all of the 32 ATP’s are made and identify their method of production as substrate level or oxidative level. 14 Explain the roles of NAD+ and FAD+ in cell respiration.

15 Explain the term “final hydrogen acceptors” and describe their significance in the cell respiratory process. Pg. 922.932 16 Contrast aerobic vs. anaerobic respiration. 17 Describe the process of protein synthesis(Central Dogma) by discussing the following reaction: DNA- (transcription)RNA’s(tRNA, mRNA, rRNA) (translation) polypeptide chain protein (via coiling, folding, and transport in the golgi and ER). Illustrate by decoding the nitrogen base sequence for a protein as done in protein model assignment. 18 Describe the role of each type of RNA in the process of protein synthesis and discuss the importance of complimentary base pairing to the process. Pg. 99, 102- 110) 19 Draw and describe the phases of mitosis pg. 98-101 20 Sketch a diagram of the cell cycle and explain it 21 State the significance of the process of mitosis in biology 24. Explain the two terms, cell division vs. cell differentiation or specialization, as they describe the two roles of cells in the body. 25. Explain how a cell’s surface area/volume ratio controls the cell’s division process.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
