Human Physiology Chapter 3 – The Cellular Level of Organization Review Chapter Study Guide This is the material you should know for the exam. Be familiar with the function of each of the cell organelles Be familiar with the structure of the phospholipid bilayer. Where is the phosphate head oriented? Is the phosphate head hydrophilic or hydrophobic? Where are the fatty acid tails oriented? Are they hydrophobic or hydrophilic? Recognize the Law of Mass Balance. What does the phrase homeostasis does not equal equilibrium mean? What is the difference between osmotic equilibrium, chemical disequilibrium, and electrical disequilibrium? What solutes are in high concentration in the ECF vs ICF? What is selective permeability? What two properties dictate whether a substance will cross the cell membrane? What is passive transport? During passive transport, in which direction will molecules move (from high to low concentration or low to high concentration)? What is diffusion and simple diffusion and what are the properties of diffusion and simple diffusion? Recognize Fick’s Law of Diffusion. What substances can pass through a lipid bilayer via simple diffusion? Can protein-mediated transport be represented by passive and active processes? What is facilitated diffusion and is it active or passive? Be familiar with the entire Na + /K + pump process and the important functions of this pump. How many Na + out and how many K + in? What is the difference between primary active transport and secondary active transport? What is the difference between phagocytosis, endocytosis, and exocytosis? What is osmosis and what is the difference between an isotonic, hypertonic, and hypotonic solution (and in which direction will the water move)? Be familiar with osmolality/osmolarity and describe, if given a solution on each side of a membrane, which direction the water will move. What is the range for blood osmolality/osmolarity? Be familiar with the negative feedback loop demonstrating the regulation of blood osmolality/osmolarity.

    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.
