After reading the paragraph below, answer the question(s) that follow(s).
As a scientist employed by the Health Products and Food Branch of Health Canada, 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.
-The method of weight loss described for Fat Away shows that the drug is acting as a metabolic
A) feedback inhibitor.
B) oxygen carrier.
C) redox promoter.
D) uncoupler.

Question

Quizplus · Accepted Answer

Fat Away makes the mitochondrial membrane permeable, allowing protons to leak across the membrane, which disrupts the proton gradient necessary for ATP synthesis in the electron transport chain. This mechanism is characteristic of an uncoupler, which disrupts the normal use of the proton gradient for ATP synthesis, leading to increased metabolic rate and, consequently, weight loss.
