Document Summary
Lactate isn"t only produced due to o2 in the muscle but also because of the speed mismatch between glycolysis and krebs" cycle, which leads to lactate acting as the proton (h+) sink for nadh"s protons. Lactate and pyruvate are formed in the muscle and may be transported to liver where the enzymes for gluconeogenesis are present (cori cycle) make glucose. Glucose is stored as a fuel for when it is needed. But they do reflect performance to some degree: maximal accumulated oxygen deficit, wingate test (anaerobic capacity over 30s) Knes 373 lecture 13 aerobic metabolism. New equations: nadh + h+ + 2. 5 adp + 2. 5 pi + o2 nad+ + h2o + 2. 5 atp and fadh2 + 1. 5 adp. Largest to smallest energy reserves: fat muscle glycogen (aerobic) muscle glycogen (anerobic) glucose phosphocreatine atp: fat metabolism = slow yield but substantial store. Muscle glycogen = fastest substrate for aerobic metabolism.
