Krebs' cycle begins with the reaction

Each molecule of pyruvic acid entering the Kreb's cycle produces:

The process by which the energy of glucose is released under aerobic respiration was discovered by

Identify the step in the tricarboxylic acid cycle,which does not involve oxidation of the substrate.

The enzymes of the $TCA$ cycle are located in the mitochondrial matrix,except for one which is located in the inner mitochondrial membrane in eukaryotes and in the cytosol in prokaryotes. This enzyme is:
