Both glycolysis and the citric acid cycle can be regulated by feedback inhibition. Provide two
examples of feedback inhibition.
What will be an ideal response?
In glycolysis, if excess ATP is present in the cytosol it binds to phosphofructokinase inhibiting
fructose-6-phosphate from being converted to fructose-1, 6-bisphosphate. In the citric acid cycle the
enzyme citrate synthase is inhibited by elevated ATP concentrations.
