Anaerobic respiration in humans occurs primarily in muscle cells during high- intensity exercise. During a 200m sprint, the heart is unable to increase peripheral blood flow at a rate to provide additional oxygen to muscles. In a human muscle cell, which one of the following statements is true? Primary source of fuel is pyruvate, and the carbon in pyruvate ends up in ethanol Primary source of fuel is pyruvate, and the carbon in pyruvate ends up in lactic acid Primary source of fuel is glucose, and the carbon in glucose ends up in lactic acid Primary source of fuel is glucose, and the carbon in glucqşe ends up in acetyl CoA
