Excess of ATP inhibits respiration by inhibiting one of the following enzymes

Excess of ATP inhibits respiration by inhibiting one of the following enzymes that are Phosphofructokinase.
Low concentrations of ATP inhibited phosphofructokinase activity by decreasing the affinity of the enzyme for the other substrate, fructose 6-phosphate. Citrate, and other intermediates of the tricarboxylic acid cycle, also inhibited the activity of phosphofructokinase.
