Document Summary
Chapter 24 part 3 |glycolysis, the krebs cycle, and the. Glucose produces 2 pyruvic acid molecules. For glycolysis to continue, nad+ must be present to accept hydrogen atoms. Nadh must donate its accepted hydrogen atoms to become nad+ again glycolysis to continue. If oxygen present, occurs in mitochondria during electron transport chain. If no oxygen present nadh gives hydrogen atoms back to pyruvic acid, reducing it lactic acid. Some leaves cell and goes to the liver. May convert into glucose-6-phosphate for storage as glycogen or. Glycolysis atp faster than aerobic respiration; atp yield far less. Fueled by pyruvic acid and fatty acids. Figure 23. 7 simplified version of the krebs (citric acid) cycle. Transitional phase converts each pyruvic acid to acetyl coa in three steps. Decarboxylation - removal of 1 c to produce acetic acid and co2. Oxidation h atoms removed from acetic acid; picked up by nad+ nadh + h+
