Where are glycolipids - Study guides, Class notes & Summaries

transport proteins - are responsible for controlling passage across the membrane fluid mosaic model - The membrane is a mosaic of protein molecules bobbing in a fluid bilayer of phospholipids fatty acid tails - nonpolar, hydrophobic fatty acid heads - hydrophilic, polar periphial proteins - bound to the surface of the membrane integral proteins - penetrate the hydrophobic core (ones that span the membrane are transmembrane protiens How do cells recognize each other? - by binding to molec...

What six functions characterize all living things? Organization Responsiveness Growth Reproduction Movement Metabolism/Excretion What is homeostasis? A steady state of internal environment of an organism. What is the difference between positive and negative feedback? Give an example of each. Positive feedback enhances change (labor contractions during birth, blood clotting, etc...) Negative feedback resists change (body temperature, insulin, cortisol, etc...) List...
