Q. Identify the prochiral molecule in the citric acid cycle

A) Oxaloacetate
B) Isocitrate
C) Citrate
D) Succinate

... Answer is B). Citrate

The citric acid cycle is the central metabolic hub of the cell. It is the gateway to the aerobic metabolism of any molecule that can be transformed into an acetyl group or dicarboxylic acid. The cycle is also an important source of precursors, not only for the storage forms of fuels, but also for the building blocks of many other molecules such as amino acids, nucleotide bases, cholesterol and porphyrin.
