refer to the two reactions below which show the first and last steps of glycolysis. The corresponding half reactions for the first and last step of glycolysis are also shown. First step of glycolysis Last step of glycolysis AG =-16.7 kl-mol Glucose AMP AG"=-31.4 k- mol Gucoveephovehate + ADP Phosphioenolpyruvate + ADP Pyravate +ATP Half reactions Hafreactionns NG" (klmol) Phosufcendpruwte 0 Pynwate -30.5 ATP is consumed in the first step and produced in the last step of glycolysis. Which of the following statements explains this observation? Select one alternative: O The enzyme-catalysed rate for the last step ofgycolysis is much higher than that of the first step. The enzyme that catalyses the first step of glycolysis has a high affinity for ATP and therefore converts it to ADP more efficiently. The last step of glycolysis takes place in a different cellular compartment and therefore occurs under different substrate and product concentrations. The conversion of phosphoenolpyruvate to pyruvate has a AG value that is more negative than-30.5 kJ. mol refer to the two reactions below which show the first and last steps of glycolysis.
