Answer:
It is never "completed." There is no end to the nitrogen cycle; Matter can neither be created or destroyed, and nitrogen is no different. Instead, nitrogen is continuously recycled from one form to another. So if the nitrogen cycle doesn't end, what happens to the aforementioned byproducts of nitrification?

That is true. Burning fossil fuels accelerates the carbon cycle.

Answer:
D- NADH
Explanation:
Nicotinamide Adenine dinucleotide, is a co-enzyme which get reduced with hydrogen atoms from Kreb;s Cycle. Flavin Adenine dinucleotide is another co-enzymes(FADH2),
Generally, NADH2 transports hydrogen atoms into the matrix of mitochondria.
The hydrogen is spit to protons and electrons.
The protons are pumped by the proton motive force(PMF) from the matrix into the intramembrane spaces.
The high concentration of protons sets up electrochemical gradients, which supplies the energy needed for ATPs synthesis by ATPase enzyme, as the proton diffuses down the electrochemical gradient back into the matrix.
Therefore the energy from glucose is inform of NADH, and this has been harnessed , for ATPs synthesis.
