Molecule G is a four carbon molecule which is formed from the Molecule F a tricarboxylic acid after it has gone through oxidative decarboxylations to yield G during citric acid cycle. Molecule F is formed from Molecule E which in turn is formed from Molecules C and D condensation. Molecule C is formed from the oxidative decarboxylation of Molecule A and Molecule D is formed from the oxidation of Molecule X. 1. Molecule X is: A. Alpha-ketoglutarate B. Oxaloacetate C....

Starting with glucose, there are five steps in the EMP/TCA pathways that produce NADH (which is converted to ATP or energy). For the step in the TCA cycle where isocitrate is converted to α-ketoglutarate, draw the chemical structures of the reactant(s) and product(s); include coupled reactions, but you don’t need to draw the structure of NAD or NADH. List the enzyme that catalyzes this reaction. Would you categorize this step as an oxidation or reduction of isocitrate? How much energy...
