as the oxaloacetate is the
substrate of citrate synthase and it change conformation of the
enzyme and which will help to bind more acetyl co A and thus km
will be reduced and Vmax will be constant.
In case of ATP, NADH AND SUCCINYL CO A ALL ARE NEGATIVE REGULATOR OF THE ENZYME THUS VMAX WILL BE CONSTANT BUT KM WI BE INCREASED WHICH MENAS MORE SUBSTRATE WILL BE NEEDED TO GAIN THE VMAX AS IT IS SHOWN IN PICTURE

the upper image which contain
the lw plot of oxaloacetate is wrong
See this image this is the right one when oxaloacetate is present.

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.
