Under anaerobic conditions, yeast carries out glycolysis to produce ATP, followed by alcoholic fermentation which produces and .

Carbondioxide and ethanol

Explanation:

After completion glycolysis under anaerobic conditions in the yeast which takes place in the cytosol, depending on the circumstances of the cell such as the yeast which is unable to carry out aerobic respiration will progress unto the anaerobic stage which is called alcoholic fermentation. This condition allows for the conversion of pyruvate formed from glycolysis to carbondioxide and ethanol that occurs with the help of two enzymes: pyruvate decarboxylase and alcohol dehydrogenase respectively.

From pyruvate to acetaldehyde

(Pyruvate decarboxylase; CO2 removal)

From acetaldehyde to ethanol

(Alcohol dehydrogenase)

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape

hope this .

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.
