Adding an intermediate to the citric acid cycle would increase the amount of substrate available for ATP production and therefore increase the rate of ATP production. Additionally, the citric acid cycle produces carbon dioxide as a waste product, so an increase in substrate availability would lead to an increase in carbon dioxide production as well.
