What would be the effect of abundant atp on the citric acid cycle?

ATP binds at the allosteric regulatory site of the enzyme that combines acetyl CoA and oxaloacetate and slows the citric acid cycle. ATP can function as an allosteric regulator of the citric acid cycle.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
