The activation of pyruvate carboxylase by acetyl-CoA should be explained.
Concept introduction:
The co-operative interaction where the binding of one molecule of a substance influences the binding of next molecules of the same kind is described to as a homotopic allosteric interaction; similarly, a heterotopic allosteric interaction involves the co-operative interaction among the different type of substances binding with a target protein.
