Whitlow’s BIO 101 Objectives:  Chapter 5 - A CLOSER LOOK AT CELL MEMBRANES Describe the general structure of a cell membrane. How does the term  fluid mosaic model  fit the cell membrane? List materials that need to be transported across the cell membrane. Into cell: Out of cell: Name 6 different types of cell membrane proteins and briefly explain their function.  Which are  integral (or transmembrane) proteins?  Which are peripheral proteins? 1. 2. 3. 4. 5. 6.

Explain the concept tonicity and describe the three possible tonicity conditions. What would happen to a cell placed in each condition? 1. 2. 3. What is turgor pressure ? What type of cells have turgor pressure ? Name 2 general types of bulk flow (larger packets of material are moved across membrane) . Differentiate between the three different type of endocytosis ; phagocytosis, pinocytosis, receptor mediated endocytosis. Explain the cell structures involved and the process of producing and maintaining a cell membrane. (hint: membrane cycling)...

    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.
