For each glucose that enters glycolysis, 10 NADH enter the electron transport chain.
- NADH and FADH, which function as electron transporters as they move through the inner membrane region, are involved in the processes of the electron transport chain.
- Electrons are transferred from NADH to the electron transport chain at complex I, where they transit through the other complexes. In this mechanism, NADH is oxidized to NAD.
- The four protein complexes of the electron transport chain use this energy to oxidize NADH and FADH2 (ETC).
- Each of the three previous stages of respiration—glycolysis, the conversion of pyruvate into acetyl-CoA, and the citric acid cycle—contributes two of the ten NADH molecules that enter the electron transport.
- The citric acid cycle contributes six of the molecules. The citric acid cycle is where the two FADH2 come from.

Answer:
In eukaryotes, recombination during meiosis is facilitated by chromosomal crossover. The crossover process leads to offspring having different combinations of genes from those of their parents, and can occasionally produce new chimeric alleles. The shuffling of genes brought about by genetic recombination produces increased genetic variation.
Explanation:
During action potential, the electrical charge inside the neuron is possible compared to the electrical charge outside the neuron.
