So things like NADH and acetylco enzyme A will also have a high concentration in the cell under resting conditions. And because under resting conditions we don't actually want to produce any more ATP molecules from the glucose, we want to conserve that glucose. What our cells will do is they will actually inactivate Pyruvate decarboxylation. How? Well, these acetylco enzymes A, the NADH molecules and the ATP molecules can actually stimulate the kinase attached onto the E two to phosphorylate the E one component of the complex. And what that does is it transforms the molecule from the active state into the inactive state.
