BIO NOTES –Cell Respiration Energy from Glucose to ATP I. Oxygen Independent (in cytoplasm) a. Glycolysis (purpose: to make ATPs!!!) i. 6-C molecule 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 ADPs -2 ATP **ATPs made thru substrate phosphorylation 3. P-C-C-C C-C-C-P 4. P-C-C-C-P P-C-C-C-P (from inorganic phosphorus) --each phosphate added to on 3-C replaces hydrogens --these H (and much energy) are picked up by the carrier molecule NAD reducing it to form NADH. (x2) 5. P ~ C-C-C ~ P P ~ C-C-C ~ P 4 ADPs 4ATPs +2 ATP 6. C-C-C C-C-C Pyruvic Acid Pyruvic Acid End Result : 2 molec. Pyruvic acid 2 molecules NADH 4 molecules of ATP (a net gain of 2 ATPs) (by substrate phosphorylation) b. Pyruvic acid anaerobic pathway i. occurs ONLY in absence of oxygen ii. allows glycolysis to take place again by freeing up NAD (NADH NAD) to accept more H's from glycolysis; to do this, NADH gives up its H's to pyruvic acid converting it to lactic acid (see ppt figs.) iii. NADH
