Assume a cell has just completed glycolysis and the resulting
pyruvate has a c-14 radio label on carbon -1. Highlight the carbon
on the attached pages as it passes through the PDH complex and the
TCA cycle until it is lost as CO2. If only a portion of the carbons
are lost stop highlighting when the CO2 first starts to come off.
