Solution

The correct option is C Glycolysis
The excess of ATP has a negative feedback mechanism on enzyme phosphofructokinase. During glycolysis when glucose-1, 6-bisphosphate is converted into Fructose-1, 6-bisphosphate, this is enzyme is used.
When there is an excess of ATP then this results in the inhibition of the activity of the enzyme phosphofructokinase. Glycolysis also cannot take place due to this.
So, the correct option is 'Glycolysis'
