The electron transport chain is also known as the respiratory chain. NADH carries electrons in the form of hydrogen atoms to the electron transport chain.
There are 16 electrons in an O2 molecule. Each oxygen atom contributes 8 electrons, totaling 16 electrons in the molecule.

A molecule of of H2O has 10 electrons: two from the hydrogen and 8 from the oxygen.
In an oxygen molecule (O2), each oxygen atom has 3 lone pairs of electrons.
There are two pairs of nonbonding electrons in a chloroform molecule. Each chlorine atom contributes one nonbonding pair of electrons, resulting in a total of two pairs of nonbonding electrons in the chloroform molecule.
A NADH molecule stores 2 electrons.
Two NAD+ molecules are needed for the breakdown of each glucose molecule during glycolysis. NAD+ is reduced to NADH during certain reactions in glycolysis, allowing it to carry electrons to the electron transport chain for further energy production.
A coenzyme called NAD is used to carry electrons in different kinds of redox reactions. NAD stands for nicotinamide adenine dinucleotide.

In glycolysis of cellular respiration, NADH produces 2ATP because one ATP is used to transport a molecule of NADH into the mitochondria and continue with aerobic respiration. However, in pyruvate decarboxylation and the Krebs cycle, each NADH yields 3ATPs. FADH2 yields 2 ATPs.
30 from one glucose molecule breakdown
3 ATP per NADH and 2 ATP per FADH2 through oxidative phosphyrolation in mitochondria
If 2 NADH molecules were produced in glycolysis, it means that 1 glucose molecule was broken down. Each glucose molecule yields 2 NADH molecules during glycolysis.
There are 16 electrons in an oxygen molecule as each oxygen atom has 8 electrons.
In my textbook it says that 1 molecule of ATP and 3 molecules of NADH are made from 1 molecule of pyruvate, via the citric acid cycle. However, since the question is asking for 1 molecule of GLUCOSE, the answer would be 2 ATP and 6 NADH since the oxidation of glucose produces TWO molecules of pyruvate, the amount of ATP and NADH would have to be doubled. I actually have this EXACT question on my exam... hmmm... do I know you by chance? o__O
