osmosis - movement of water across a semi-permeable membrane osmotic pressure: definition - the force that attracts water across a semi-permeable membrane water attractors in osmosis - - sodium - albumin passive diffusion - - solutes crossing a semi-permeable membrane down a concentration gradient - No ATP needed facilitated diffusion - - solutes moving across a semi-permeable membrane from low concentration to high - ATP required anaerobic respiration - Respiration that does not require oxygen aerobic respiration - Respiration that requires oxygen where does the Krebs cycle take place? - mitochondria Krebs cycle: Aerobic respiration important characteristic - - produces a bunch of ATP - no byproducts Krebs cycle: Anaerobic respiration important characteristics - - produces 2 ATP - byproducts: pyruvic acid, lactic acid - leads to metabolic acidosis - temporary Na+K+ pump - uses ATP to keep K+ inside cell and Na+ outside cell to create resting potential (2:3 ratio)
