NADH
In cellular respiration, oxygen is the final electron acceptor at the end of the electron transport chain. In the absence of oxygen methylene blue can substitute as this electron acceptor. In its oxidized state, methylene blue is blue in color. However, in its reduced state, methylene blue becomes colorless or clear. Consequently, if methylene blue is added to a solution in which cellular respiration is occurring and oxygen is unavailable, the solution will become colorless or clear.So,the substance that have same function as methylene in living thing is coenzyme such as NAD+.

To make the Eosin Methylene BLue Agar look cool and hip.
function of eosin methylene blue agar (EMB)
When you added methylene blue to the living yeast cell, the methylene blue is actually a dye so you could see the cells, therefore, the yeast cell became blue. It is much the same with hair dye. If you have a bottle of blue hair dye, it will dye your hair blue.
Polluted water sample will decolorize the methylene blue solution faster than a pure water sample.
Active enzymes within living cells cause methylene blue to become colorless. Since dead yeast cells have inactive/denatured enzymes, the methylene blue stays blue.

i think the methylene blue will be make aqua blue because the charcoal will penerate the color of methylene blue,,,there are absorption process,,,in the charoal between the methylene blue.... (kharlz)
because methylene blue turns colourless when it is reduced by hydrogen. during respiration hydrogen is produced and instead of reducing NAD, it reduces methylene blue and turns methylene blue colourless. if methylene blue goes from blue to colourless then this shows that the cell is respiring as it is producing a suffiecient amount of hydrogen to decolourise methylene blue
Methylene Blue
Methylene blue is used as an indicator for the presence of certain Ions such as the presence of HS - ion. spectrophotometry is used once the methylene blue has reacted to determine the quantity of said ion based on the intensity of blue that the reacion produces. Using a spectrophotometer you can determine the intensity and compare it with a set scale that has been calibrated with known concentrations of this ion.
