Jim Bidlack - BIO 1304 GENERAL BOTANY Lecture 11 - I. Overview A. 2 fixation) - chloroplasts B. 1. Glycolysis - cytoplasm 2. Krebs (Citric acid cycle) - mitochondrion 3. II. Glycolysis [glucose and fructose from Calvin cycle (photosynthesis)] A. Glucose - glucose-6-p - fructose-6-p - fructose 1,6-dp - PGAL (=DHAP) - 1,3-dp-glycerate - 3-p-glycerate - 2-p-glycerate - phosphoenolpyruvate - pyruvate B. Initial step(s) - energy requiring (2 ATP) C. Subsequent steps 1. Two - substrate-level phosphorylations (4 ATP) 2. One - reduction of NAD to NADH (2 NADH) D. E. Final product - 2 pyruvates III. Alternatives after glycolysis A. Lactic acid - 2 ATP (no NADH) . .. intense muscle activity (little O 2 available) B. Ethanol - 2 ATP (no NADH) . .. fermentation C.
