Methylene blue is used as an indicator in a yeast suspension does it affect the suspension?

http://www-saps.plantsci.cam.ac.UK/records/rec300.htm states that methylene blue indicates reducing and oxidising conditions by reacting to presence or absence of protons but is not involved in the reaction itself. This suggests that it wouldn't affect the suspension.
However, I have previously read that methylene blue accepts protons during respiratory reactions, reducing the protons availble for energy release. This suggests that it would affect the suspension.
I cannot remember where I read this second statement but I believe the source from which the first statement was taken is more reliable.

What is yeast suspension?
A yeast suspension is made by mixing yeast cells with a liquid.
Why methylene blue can act on only dead yeast cells but not on live yeast cells?
Active enzymes within living cells cause methylene blue to become colorless. Since dead yeast cells have inactive/denatured enzymes, the methylene blue stays blue.
Process name involved the reaction of yeast and methylene blue?
Methylene blue is a solid, odorless, dark green powder at room temperature. In water this chemical compound turns into a blue solution. When methylene blue is reacted with yeast cells it inhibits the respiration which stops the cells from using hydrogen ions to release energy.
Yeast reaction with methylene blue?
yes,because yeast can undergo both ae reobic and anaerobic respiration.
When living yeast cell were place in methylene blue they became blue why did this happen?
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.
What is yeast an indicator of?
yeast is an indicator of sugar. it blows up (puffs up) when it is both put in hot water
Dead boiled yeast suspension?

Can you use determiners like 'a' and 'the' with yeast?
The test determined that she had a yeast infection. After you have prepared the basic ingredients add the yeast suspension to the dough and knead.
Is itching a symptom of a yeast infection?
Yes, itching can be a symptom of a yeast infection. That is not the only symptom but could be an indicator.
What does yeast affect?
Nutrition
How can you use yeast as an indicator to see if theres sugar in a material?
it can be used becase if you add water you will see the yeast and the bubbling stuff you know
Can you move beer during fermentation?
Yes, no problem with that. Keep the enough yeast in suspension.
