A falcultative anaerobic organism is able to perform aerobic respiration in the presence of oxygen and fermentation in the absen
ce of oxygen. An example of a falcultative anaerobic organism is brewer's yeast, which is used in the production of alcoholic
beverages. If sealed in a vessel containing oxygen gas, water, and sugar (glucose), the yeast will eventually deplete the oxygen
gas. As long as glucose is available, however, the yeast can still survive.
Brewer's yeast use oxygen preferentially because???
The animal cells get the organic compounds by eating plants. The only form of energy a cell can use is a molecule called adenosine triphosphate (ATP). Chemical energy is stored in the bonds that hold the molecule together.
