Question

Yeast can perform both anaerobic and aerobic respiration. Does the experiment demonstrate this fact? Explain your reasoning.

a) True
b) False

Answer 1

Yeast can perform both anaerobic and aerobic respiration. In anaerobic respiration, yeast carries out alcoholic fermentation, producing ethyl alcohol (drinking alcohol) and carbon dioxide gas. In aerobic respiration, yeast uses oxygen to break down glucose into carbon dioxide and water, producing a larger amount of ATP compared to fermentation.

Step-by-step explanation:

Yeast can perform both anaerobic and aerobic respiration. In anaerobic respiration, yeast carries out alcoholic fermentation, producing ethyl alcohol (drinking alcohol) and carbon dioxide gas. This process is used to make common food and drinks, such as bread and wine. In aerobic respiration, yeast uses oxygen to break down glucose into carbon dioxide and water, producing a larger amount of ATP compared to fermentation.
