As a Scientist Employed by the FDA, You've Been Asked

As a scientist employed by the FDA, you've been asked to sit on a panel to evaluate a pharmaceutical company's application for approval of a new weight loss drug called Fat Away. The company has submitted a report summarizing the results of their animal and human testing. In the report, it was noted that Fat Away works by affecting the electron transport chain. It decreases the synthesis of ATP by making the mitochondrial membrane permeable to H+, which allows H+ to leak from the intermembrane space to the mitochondrial matrix. This effect leads to weight loss.
-You predict that a side effect of Fat Away will be increased

A) production of NADH.
B) production of pyruvate.
C) production of lactate.
D) body temperature.
