A mitochondrial membrane complex consisting of ATP synthase, adenine nucleotide translocase (ATP-ADP translocase), and phosphate translocase functions in oxidative phosphorylation. Adenine nucleotide translocase, an antiporter located in the inner mitochondrial membrane, moves ADP into the matrix and ATP out. Phosphate translocase is also located in the inner mitochondrial membrane. It transports H ions and phosphate (H2PO4–) ions into the matrix.

Expert Solution

a mitochondrial membrane complex consists of ATP synthase, adenine nucleotide translocase, and phosphate translocase functions in oxidative phosphorylation. adenine nucleotide translocase an antiporter, transporter located in the inner mitochondrial membrane, transports ADP and ATP across the membrane. phosphate translocase a symporter, located in the inner mitochondrial membrane, it transports H+ and phosphate across the membrane. 4 H+ ions are required to be moved across the membrane for the synthesis of 1 ATP. into the mitochondrial matrix is ADP^3- transported during times of active oxidative phosphorylation.

the electrochemical gradient (membrane potential) drives the transport of adenine nucleotides.

1 ADP transported for each 1 ATP is the ratio of ADP to ATP transported by the adenine nucleotide translocase.

H+ and H2PO4- are transported into the matrix in a process driven by the proton gradient drives the transport of H2PO4- across the membrane direction is it transported during oxidative phosphorylation.

You can create a vesicle from the inner mitochondrial membrane that includes a functional ATP synthase protein with its fully functional F0 rotor, central stalk, and F1 ATPase head. There is ATP, ADP, and Pi (inorganic phosphate) present inside and outside of the vesicle. You are allowed to mechanically spin the F0 rotor domain in the absence of protons. How would ATP levels change inside the vesicle? Briefly explain how this change occurs.
