Question

How yeast breathes. Is it the same as human and how they can comparable with human beings if yes.?

Answer 1

What is yeast breath? It is nothing more that CO2 or carbon dioxide. Yeast is a living organism and in the presence of air (oxygen), it breaks down sugar to produce CO2, water and energy (aerobic respiration). But guess what? Yeast can survive in an environment without oxygen. In this case, the sugar is incompletely broken down to produce CO2, alcohol and energy (anaerobic respiration). This process is called fermentation, as defined by Pasteur . Now, are you thinking, "how does the concentration of sugar affect the rate of fermentation"? Though so. The web site, How Long Will I Be Blue: A Yeast Fermentation Lab *, attempts to answer that question. Take a look. Of course, we all know that yeast is used in making bread.

we breathe in oxygen and breathe out CO2.B
