In mammals body temperature can be regulated by uncoupling electron transport and oxidative phosphorylation. An inner mitochondrial membrane protein called (appropriately enough) uncoupling protein 1 or UCP1 allows protons to flow from the intermembrane space back into the matrix, bypassing ATP synthase. Interestingly, the same protein has been identified in some plants, where it's also important for thermogenesis. Skunk cabbage, for example, can maintain its temperature 15-35 degrees C above ambient temperatures for months during the winter in this way. If you were to carry out an experiment measuring various metabolites associated with cellular respiration while "uncoupling" is taking place you would expect to see
a. an increase in starch metabolism, an increase in ATP synthesis and an increase in oxygen consumption
b. an increase in starch metabolism, an increase in ATP synthesis and a decrease in oxygen consumption
c. an increase in starch metabolism, a decrease in ATP synthesis and an increase in oxygen consumption
d. a decrease in starch metabolism, an increase in ATP synthesis and an decrease in oxygen consumption
e. None of the above is likely
