Document Summary

Focus: the cell membrane represents a fundamental aspect of life the ability to maintain an internal environment as distinct from your extracellular environment. Important concepts include the amphipathic nature of phospholipids and the different types of membrane associated proteins (integral and peripheral) and their respective functions. As well, there are many different transport mechanisms across the semi- permeable biological membranes that are important to distinguish. Describe, in detail, the phospholipid bilayer and identify its components. Draw an intact biological membrane and all of its components. Know the difference between peripheral and integral membrane proteins. Describe 4 different ways to get a solute across the membrane. Understand the difference of passive and active transport mechanisms. Understand the contributions and influence of both electrical and chemical gradients biological membrane across the membrane. Define: fluid mosaic model, compartementalization, integral membrane protein, peripheral membrane protein, phospholipid, cholesterol, glycoprotein, glycolipid, selectively permeable, osmosis, passive diffusion, active transport, facilitated diffusion, , endocytosis, phagocytosis, exocytosis.
