Weight loss was dramatic in patients taking this drug. However, to quote Efraim Racker (A New Look at Mechanisms in Bioenergetics, Academic Press, 1976, p. 155), ..."the treatment eliminated not only the fat but also the patients,...This discouraged physicians for awhile..." This drug works for weight loss, by causing the leakage of H+ across the inner mitochondrial membrane. Which of the following would you expect to see in patients taking DNP? Select the best answer. Question options: decreased ability to produce ATP increased ability to produce ATP decreased ability to use Krebs cycle to produce ATP slowing down the citric acid cycle.18.
