Membranes Stration Review Transport Diffusion ___ Diffusion Active Tangent Cell Size variations Assembly = Phophalipid Hormone replacement theorpy taking phytosterols after menopause Surface membranes have carbohdrates associated with them. Short Distance Transport: Long Distance Trans: Oxygen into the lungs into the blood cells and bloodcells throughout the body. Most multicelluar organisms require a circular system. Diffusion : Is a physical redistribution process. o Powered by Knetic energy of molecules. o Until quilibrium is established o Glycine 50microne in less than 1 second. 1-2m = 8 years! Non – Linear relationship between distance and time. Rate of Diffusion o Atom Molecule o Temp UP o Conc Gradient o Cout – Cin/X = DeltaC/DeltaX
