Question
(c) What is the ratio of ADP to ATP transported by the adenine nucleotide translocase? That is, how many UP are transported for each ATP transported? (d) What drives the transport of H2PO4^- across the membrane? Which direction is it transported during oxidative phosphorylation? H2PO4 is transported into the matrix in a process driven by ATP hydrolysis. W and HPO4 are transported into the matrix in a process driven by the proton gradient. H2PO4 is transported out of the matrix as H enters through AW synthase. H2POC is transported out of the matrix in a process driven by the electrochemical gradient. The adenine nucleotide translocase (ADP-ATP translocase), a transporter located in the inner mitochondrial membrane, transports ADP and ATP across the membrane. It is an antiporter. (Recall that these adenine nucleotides are negatively charged: ADP and ATP.) Phosphate translocase is also located in the inner mitochondrial membrane. It transports H and phosphate (h2P04) across the membrane. It is a symporter. Answer parts (a). (b). (c), and (d) below. (a) Which direction is ADP^3- transported during times of active oxidative phosphorylation? (b) What drives the transport of adenine nucleotides? (c) What is the ratio of ADP to ATP transported by the adenine nucleotide translocase? That is, how many ADP are transported for each ATP transported?Explanation / Answer
1. out of mitochondria
2 electrochemical gradiant
3. 1adp:1atp
4. by atp hydrolysis
