Which gas is produced during fermentation in yeast and to which process is it linked?
Answer and explanation
Correct answer: Carbon dioxide and anaerobic respiration
In yeast fermentation, glucose is broken down without oxygen. This anaerobic pathway produces ethanol and carbon dioxide, so carbon dioxide bubbles are released in processes such as bread making. Therefore option B is correct. Oxygen is used in aerobic respiration rather than produced by ordinary yeast fermentation, while nitrogen, hydrogen, photosynthesis, and excretion do not describe this reaction.
