Document Summary

Ionization of water: @25 degrees celsius, henderson-hasselbalch equations. Important ph buffers in biological systems are weak acids and their salts: buffer = phosphate, regulator = bicarbonate, ph effects protein structure and enzymatic activity, rcooh -> rcoo- + h, rnh2 + h+ -> rnh3+ Lipids and water: triglycerides, fatty acids, phospholipids, steroids, water and electricity, conductivity of water is relatively low, electrolytes increase the conductivity of aqueous solutions, ohms. I or current is the flow of electric charge. Inducible: allosteric regulation, covalent modulation, e. g phosphorylation and dephosphorylation. Bisc306 general (animal) physiology lecture 2: fluid, phospholipid bilayer which includes a polar head and a nonpolar tail forming the membrane. Within this membrane are various gated channels and proteins controlling the flow and regulation of ions and minerals into the cell: glycerophospholipid, sphingolipids, sterols, protein, fick diffusion equation. If cells swell in a solution, then that solution is said to be hypotonic.
