February 2, 2001 HOUR TEST 1 NAME_____________________ ( 6) 1. The free energy change of a chemical reaction varies with the concentration of reactants and products. The relationship is given by the reaction isotherm: G = G o ' + RTlnQ' (a) What is the significance of the prime (') in G o ' and Q'? Page Points 1 ____ 2 ____ 3 ____ 4 ____ Total ______ (b) What is the relationship between Q' and K' eq for a spontaneous reaction? (10) 2. Reactions near equilibrium have G values low, near zero, while reactions that are irreversible or far from equilibrium have large negative G values. In the list of enzymes of glycolysis and the TCA cycle listed below, but a check by the enzymes that operate near equilibrium . hexose phosphate isomerase citrate synthase triose phosphate dehydrogenase isocitrate dehydrogenase succinate dehydrogenase malate dehydrogenase phosphoglycero mutase alpha keto glutarate dehydrogenase 3-phosphoglycerate kinase phosphofructokinase (8) 3. Starting with [1- 14 C]-glucose, predict which carbon(s) would be labeled in the following intermediates after glycolysis and during the first turn of the TCA cycle. (Draw the structure of the intermediate and circle the labeled carbon atom). (a) pyruvate
