Document Summary
Blood lactate = la () >50 mmol/l. 21 days of racing (two rest day) Both fat and cho may be used aerobically, fat cannot be used anaerobically. Adp + pi + o2 = atp. Utilizing oxygen with adp to give us atp. If skeletal muscle, it is fadh not nadh. If exercise intensity is low enough, and oxygen is available, then pyruvate produced in glycolysis may more into the mitochondria to be changed to acetyl coa via the pyruvate dehydrogenase complex. The acetyl coa is broken down in krebs cycle (tricarboxylic acid or tca or the citric acid cycle) the krebs cycle produces carbon dioxide (co2) and hydrogen (h2) Regulatory enzymes: citrate synthase and isocitrate dehydrogenase. Co2 is being released in the pyruvate-acetyl coa reaction. Know there is two placed where co2 is produced metabolically. Aerobic metabolism there is 3 nadh + h. 1 pair of hydrogens associated with fad.
