Lecture Outline 4 Membrane Physiology Silverthorn Ref. Chapters 3 & 5 – 6 Learning Objectives for Understanding Membrane Physiology 3 & 5 – 6.1. List the functional purpose of the plasma membrane 3 & 5 – 6.2. Explain the hydrophobic, protein, and carbohydrate chemistry of the plasma membrane by their functions 3 & 5 – 6.3. Describe the structures of plasma membranes that create attachments and use tissue examples of where to locate them 3 & 5 – 6.4. Define and explain the forces that allow or inhibit movement across the membrane 3 & 5 – 6.5 Define the methods of plasma membrane transport in terms of energy cost 3 & 5 – 6.6. Define the fluid compartments by solute concentration and explain how the isoosmotic environment is achieved through osmosis 3 & 5 – 6.7. Define diffusion and explain the influences on rate of diffusion 3 & 5 – 6.8. Describe how the membrane controls molecule diffusion 3 & 5 – 6.9. Explain the need for active transport and define the molecules moved with this method 3 & 5 – 6.10. Explain why the active transport of Sodium and Potassium is a requirement of cell life 3 & 5 – 6.11 Describe how the cell manipulates sodium movement as an energy source for secondary active transport 3 & 5 – 6.12. Define the selectiveness of receptor mediated membrane transport and use lipid movement as an example of how this maintains a level of controlled movements 3 & 5 – 6.13. Define the types of membrane communication and use examples for the chemical forms 3 & 5 – 6.14 Contrast the difference between nonpolar and polar communication signals 3 & 5 – 6.15 Define Signal transduction and Explain the process for the differing chemical signal types 3 & 5 – 6.16. Explain the kinds of changes forced upon the cell by chemical signals Key Terminology Attachment, Apical Surface – Basilar Surface, Hydrophobic, Hydrophylic, Lipophylic, Lipophobic, Ion, ICF, ECF, Solute, Phospholipid, Glycoprotein, Transmembrane, Peripheral, Cytoplasmic,

    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.
