Document Summary
Lecture 6 energy production: atp breakdown & re-synthesis. Atp + h2o adp + p + energy use to power all biological work. 2 locations of atp production/re-synthesis = mitochondria (etc, krebs aerobic), cytosol (anaerobic glycolysis). Limited quantities, continuous re-synthesis, levels only under extreme condition, >80-100g always. Pcr = provides some energy for atp re-synthesis, 4-6x more pcr than atp, maximal energy 10s. 3adp + 3pi + nadh + h+ + o2 = 3atp + nad+ + h2o. Glycolysis: regulated by series of enzymes, 5% of atp release, o2, substrate-level phosphorylation, intense exercise pyruvate + h lactate. Cac = 2nd stage of energy release 8 x (nadh + h+), 2 x (fadh2), 2 x [atp (gtp)], 6 x (co2) = 34 gross atp = 32 net [4 from slp (glycolysis + cac), 28 from ox. phos. ] Per kilogram of skeletal muscle mass = 3 to 8 mmol of atp and 4-5x more pcr.
