Biology

During strenuous activity, the demand for ATP in muscle tissueis vastly increased. In rabbit leg muscle or turkey flight muscle,the ATP is produced almost exclusively by lactic acid fermentation.ATP is formed in the payoff phase of glycolysis by two reactions,promoted by phosphoglycerate kinase and pyruvate kinase. Supposeskeletal muscle were devoid of lactate dehydrogenase. Could itcarry out strenuous physical activity; that is, could it generateATP at a high rate by glycolysis? Explain.

Discuss the pros and cons of lactate production in active muscle.Why is lactate produced? What happens to the lactate?

The transformation of glucose to lactate in myocytes releases onlyabout 7%
of the free energy released when glucose is completely oxidized toCO₂ and H₂O. Does this mean that anaerobicglycolysis in muscle is a wasteful use of glucose?

1 During strenous exercise muscle cells carry out lactic acid fermentation due to lack of oxygen for aerobic respiration to occur Lactate dehydrogenase is the main enzyme in lactic acid fermentation which converts pyruvate to lactate with simulatenous interconversion of NADH and NADLDH deficiency is a condition in which body has to decide how to break sugar especially in skeletal muscle cells If LDH is lacking in muscle cells it could be either deficiency in lactate dehydrogenaseA or See Answer
