Document Summary

Metabolism-- two chemical processes; utilizing and using fuel. Chemical: energy stored in the body; glucose, fat, glycogen, atp. Mechanical: energy that allows work to be performed; chemical to mechanical energy allows w. Stored chemical energy in carbs, fats, and proteins. Humans need o2 for respiration and need chemical energy to metabolize. Especially in excess of carbs and alcohol or calories. Suggests they will be oxidized in the mitochondria. We can mobilize these fats into the blood stream. We need to get fa into the cell. Beta oxidation: cleaving off two carbons of whatever molecule you have (18carbon) Left with acyl group (16 carbon) + acetate (2c) Here we make citric acid and coa for the krebs cycle. Atp produced per unit of o2 consumed 6 moles of o2= 38 atp 26 moles o2= 145 atp. If you have limited amounts of o2, the most efficient energy use is carbs. Relationship between co2 volume produced to volume of o2 consumed.
