Factors That Makes FADH Produce Less ATP
According to the findings that were posted on Jove website, FADH produces less ATP since it joins electron distribution chain at a final stage unlike NADH which initiates electron transport process. It was further established that the electron chain consists of carrier ions that are joined to form 3 protein elements. These three groups are responsible for generating enough energy that’s equivalent to one ATP for every group. If you want to provide specific answers to a question of why the oxidation of FADH will produce less ATP of about 1.5, you need to look at the number of protons that are activated by each compound.
Molecular scientists believe that FADH always produces less energy because the numbers of protons that it activates are fewer when compared to NADH. Similarly, the amount of energy produced by FADH is usually affected by the amount of oxygen that’s circulating in your cells. For example, when oxygen levels in your blood reaches a record low, it will stop any process that will result in the formation of ATP.
The shutting down of this process will cripple all the metabolic reactions that are needed in transportation of hydrogen ions across the membranes. Its effect will be the inability of your cell to maintain an existing proton gradient. Once this problem is witnessed in your cells, this will cause the breakdown of ATP synthesis process that’ll also have a direct impact on the amount of energy produced.
Since a total of six protons are pumped from FADH to the membrane of mitochondrion, then the amount of ATP that will be produced will be equal to 6/4= 1.5. Above all, FADH plays an important role when promoting respiration processes in your cells. It is worth stating here that NADH together with FADH are created during the process of respirations and play a collective responsibility of ensuring that molecules are moved into mitochondria.
