Chapter 7 Making ATP (Energy from Food) Oxygen Independent: doesn’t need oxygen o Glycolysis o Pyruvic acid anaerobic pathway Oxygen Dependent: needs oxygen o Electron Transport (Cytochrome) system o Pyruvic acid aerobic pathway Make ready step Krebs Citric Acid Cycles Cells need food for energy and growth, and for building blocks Oxygen Independent in Cytoplasm o Glycolysis 6 carbon molecules glucose C 6 H 12 O 6 1 . C-C-C-C-C-C 2. P- C-C-C-C-C-C -P 2 ATPs 2 ATPs o Substrate phosphorylation 3. P- C-C-C C-C-C -P 4. P- C-C-C - P P - C-C-C -P o Each phosphate added to one 3-C replaces hydrogens. o These H (and much energy) are picked up by the carrier molecule NAD reducing it to form NADH. (x 2) 5. P ~ C-C-C ~ P P ~ C-C-C ~ P o ~ = high energy bonds 4 ADPs 4 ATPs 6. C-C-C C-C-C Pyruvic Acid Pyruvic Acid At end of Glycolysis: o 2 molecules of Pyruvic acid o 2 molecules of NADH o 4 molecules of ATP (a net gain of 2 ATPs) (by substrate phosphorylation)
