Glycolysis starts with one molecule of glucose and ends with two pyruvate (pyruvic acid) molecules, a total of four ATP molecules, and two molecules of NADH. Oxidative phosphorylation could not occur without glycolysis and the citric acid cycle, because_____. However, in eukaryotes, the NADH produced in the cytoplasm (during glycolysis) must be brought to the mitochondria for oxidative phosphorylation. Before we begin the next lesson let us see how well you remember your lesson about the parts of the mitochondrion. 1. Beginning with a single molecule of glucose and ending with glucose-6-phosphate, the first reaction requires the use of a hexokinase enzyme to break down an ATP, converting it to ADP, in order to phosphorylate the glucose molecule. Carbon dioxide is produced in the Krebs cycle. Anaerobic glycolysis is only an effective means of energy production during short, intense exercise, providing energy for a period ranging from 10 seconds to 2 minutes. However, at the end of glycolysis, four moles of ATP are produced, resulting in the production of net 2 moles ATP from each mole of glucose. 28-10 The end product of glycolysis, pyruvate, cannot enter as such into the citric acid cycle. Overall, glycolysis produces two pyruvate molecules, a net gain of two ATP ATP alone is actually a competitive inhibitor of hexokinase. Phospho-fructo kinase will then catalyze another phosphorylation reaction, adding another phosphorous group to the fructose-6-phosphate, creating fructose-1,6-bisphosphate.
