If you were to add one of the eight citric acid cycle intermediates to the culture medium of yeast growing in the laboratory, what do you think would happen to the rates of ATP and carbon dioxide production?
A) There would be no change in ATP production, but we would observe an increased rate of carbon dioxide production.
B) The rates of ATP production and carbon dioxide production would both increase.
C) The rate of ATP production would decrease, but the rate of carbon dioxide production would increase.
D) Rates of ATP and carbon dioxide production would probably both decrease.

Adding one of the citric acid cycle intermediates to the culture medium would increase the availability of substrate for the cycle, leading to an increase in both ATP and carbon dioxide production. The citric acid cycle generates ATP and releases carbon dioxide as a byproduct of the oxidation of acetyl-CoA. Therefore, providing more intermediates for the cycle would boost its function and increase the rates of ATP and carbon dioxide production.
