Document Summary

Cells are quite efficient, they store about 40% of the energy released from the breakdown of glucose in bonds of atp. Complete glucose breakdon c6h1206 +6o2 6co2 +6h2o + chemical energy (atp) + heat. After glycolysis there are two possible pathways: cellular respiration occurs if oxygen is available (aerobic, fermentation occurs if oxygen is not available (anaerobic) Series of 10 reactions each catalyzed by its own enzyme. Glycolysis has two parts: glucose activation, energy harvesting. Four atp generated, but 2 atp were used. Also generate 2 molecules of nadh before glucose can be broken down it must be activated-stable glucose to unstable fructose 1, Cells can chemically transform a variety of foods into fat if the foods are consumed in excessive amounts. (our cells don"t need more atp) The chemical pathways of breaking down glucose also produce fat. When you eat lots of sucrose (candy bars, soda, sports drinks, etc. ) Both enter glycolysis and are converted to g3p.
