Which of the following is TRUE about mitochondrion?
|
ATP Synthase is located in the outer mitochondrial membrane. |
|
ATP synthase pumps Na+ and K+ across the mitochondrial membrane to power the electron transport chain. |
|
The electrochemical gradient of Na+ across the mitochondrial membrane drives the generation of ATP. |
|
The pH in mitochondrial matrix is higher than that in cytoplasm. |
The pH in mitochondrial matrix is higher than that in cytoplasm.
( pH nearly 7.8 compare to 7.0-7.4 in cytoplasm. H+ ion power the ATP synthesis in the ATP synthase at the inner membrane of mitochondria.)
Thank you.............

What happens when ATP synthase operates “in reverse” and pumps H+ across a membrane against its electrochemical proton gradient? Choose one: ATP is hydrolyzed to form ADP and Pi. ATP is co-transported across the membrane. Nutrients are transported in the opposite direction across the membrane. Na+ is transported in the opposite direction across the membrane. ATP is synthesized from ADP and Pi.
