These membranous vesicles seal inside out, so that the intermembrane space of themitochondria becomes the lumen of the submitochondrial particle. Explain (or diagram) the process of electrontransfer and oxidative phosphorylation in these particles. Assuming all the substrates for oxidativephosphorylation are present in excess, does ATP synthesis increase or decrease with an increase in the pH ofthe fluid in which the submitochondrial particles are suspended? Why?Normally, the flow of electrons to O2 is tightlylinked to the production of ATP via the electrochemicalgradient. If ATP synthase is inhibited, for example, elec-trons do not flow down the electron-transport chain andrespiration ceases. Since the 1940s, several substances—such as 2,4-dinitrophenol—have been known to uncou-ple electron flow from ATP synthesis. Dinitrophenol wasonce prescribed as a diet drug to aid in weight loss. Howwould an uncoupler of oxidative phosphorylation pro-mote weight loss? Why do you suppose dinitrophenol isno longer prescribed?
