ATP synthesis in cell requires

Options

A. `H^(+)` gradient across the membrane
B. `K^(+)` gradient across the membrane
C. `PO_(4)^(3-)` gradient across the membrane
D. `Ca^(2+)` gradient across the membrane

Answer

A

Explanation

ATP synthesis takes place by the process of chemiosmosis, where ATP is genterated via pronon `(H^(+))` gradient across the membrane. As proton moves from inside to outside across a membrane some configuration change occurs in the ATPase which start catalysing formation of ATP.
