Biology Notes August 30 SPONCH elements- most prevalent in body Sulfur Phosphorus Oxygen Nitrogen Carbon Hydrogen Neutron, Proton=1 amu Isotopes different numbers of neutrons C13 means 6 protons 7 neutrons Covalent Share Ionic Gain or Loss Antioxidants neutralize free radicals(ex. Oxygen with less or more than 8 electrons) Cation- positively charged ion Anion- negatively charged ion WATER IS NOT THE UNIVERSAL SOLVENT, it is the solvent of earth September 4, 2007 Homeostasis- Maintains body to a certain status 7.2-7.4 ph in the body pH of 5 has a H+(hydroxide)concentration of 9 or 10^-9 September 6, 2007 Buffer- is a substance that can maintain the pH of a solution(binds to H+ or OH- to maintain pH) Hemoglobin is a buffer, in your red blood cells Albumin is buffer, in your blood plasma Bicarbonate Ion HCO3-, in your blood plasma and in red blood cells
