A reduced amount of ADP causes accumulation of precursor NADH which in turn can inhibit a number of enzymes.
An additional level of regulation is introduced by the transport rates of ATP and NADH between the mitochondrial matrix and the cytoplasm.
Each round of this cycle reduces the length of the acyl chain by two carbon atoms and produces one NADH and one FADH 2 molecule, which are used to generate ATP by oxidative phosphorylation.
In the glycerol phosphate shuttle electrons from cytosolic NADH are transferred to dihydroxyacetone to form glycerol-3-phosphate which readily traverses the outer mitochondrial membrane.
Glutamate-5-semialdehyde is first formed by glutamate 5-kinase (ATP-dependent) and glutamate-5-semialdehyde dehydrogenase (which requires NADH or NADPH).
If the cycle were permitted to run unchecked, large amounts of metabolic energy could be wasted in overproduction of reduced coenzyme such as NADH and ATP.
