Although the direct reduction of CoQ to CoQH2 is thermodynamically possible, this reaction is not a direct part of the electron
Nady [450]

Answer:

This electron handoff from NADH to FMN, as opposed to direct reduction of CoQ by NADH, a critical component of the electron transport chain is important for Signaling Transduction and Metabolomics

Explanation:

The NADH-CoQ reductase reaction is catalyzed by Complex I. In this course of activity, following events takes place-  

a) FNM (NADH dehydrogenase flavoprotein) is reduced by the NADH  to FMNH2 through following reactions –  

NADH+H++E-FMN↔NAD++E-FMNH2

b) In the next phase coenzyme Q  receives electron from FMNH2  through the the iron–sulfur centers of the NADH-CoQ reductase

c) The iron atom undergoes oxidation–reduction cycles to conserve  mitochondrial protein  as lataxin and hence transport protons from the matrix to the intermembranal space thereby Signaling Transduction and Metabolomics

The parasites include protozoans, like as the agents of sleeping sickness, malaria, and amoeba dysentery; animals, like lice, hookworms, mosquitoes, and vampire bats; fungi, like the agents of ringworm, honey fungus; and plants, like dodder, mistletoe, and the broomrapes.

Action AA batteries last four times as long as Bonus AA batteries. Action AA batteries also cost four times as much as Bonus bat
Feliz [49]
Since the Action AA batteries last 4 times as long as Bonus AA ones, even though they cost four times as much for convenience in only having to change them once compared to 4 times for the same length of time, this is a good reason to buy them. This is especially the case if the batteries are being used in a remote place such as by a geologist with a GPS out in the bush then he/she doesn't have to worry about them running down so much.
