Document Summary

Electron transfer is going to play a major roles in pathways. Delivers 2 electrons and 1 proton to nad+ nadh. Other proton is released into the surrounding solution. Involved in synthesis of atp [fig 9. 4: nadh molecules- stored energy, introduction, sunlight [fig 9. 2, food, digestive system. Transfer of electrons from the nutrients and they go through redox (30 enzymes: process of about ~30 steps. Each step has its own enzyme: glucose- common starting material for many cells, c6h12o6 + 6o2 6co2 + 6h2o + energy, reactants glucose and oxygen. Glycolysis: enters the cell via transport protein glut 1, cytosol (occurs here, 2 phases, energy investment phase --- *endergonic required atp. Glucose c-c-c-c-c-c take 2 atp and split off terminal. P-c-c-c-c-c-c-p phosphorylation reaction: fructose -1 phosphate 2 adp biphosphate. Take nad+ an reduced to nadh + h+ (h removed from g3p, g3p is oxidized) 2 atp and 2 adp are produced.
