DNP (2,4-dinitrophenol) is an effective weight-loss agent that was used in diet pills in the 1930s
It has since been removed from the market (though it is available online) because of
serious side effects such as fever, cataracts, rashes, and sometimes death. DNP inserts into
the inner mitochondrial membrane and shuttles protons between the intermembrane space
and the matrix. Based on this information, which of the following might you predict?
What will be an ideal response?
reduced ATP production
dissipation of the proton gradient
decreased difference in pH between matrix and intermembrane space
