Respiratory quotient (RQ). This classic metabolic index is defined asthe volume of CO2CO2 released divided by the volume of 0202consumed. Voa. Calculate the RQ values for the complete oxidation of glucose andof tripalmitoylglycerol.b. What do RQ measurements reveal about the contributions ofdifferent energy sources during intense exercise? (Assume thatprotein degradation is negligible.)

a) describe the overall reaction catalyzed by the pyruvate dehydrogenase Situational Problems I. Oxidative decarboxylation of pyruvate and the TCA cycle in muscles are stimulated by increased aerobic excrcise. These processes operate only when O, is present, although oxygen does not participate directly in these processes. Explain why oxidative decarboxylation of pyruvate is activated under aerobic conditions. For the answer: a) describe the overall reaction catalyzed by the pyruvate complex (PDH) and its regulation; b) outline the intermediates and enzymes of the TCA cycle; c) explain the relationship between the reactions of PDH and the TCA cycle and the respiratory chain.
