Which of the following statement(s) concerning ATP synthesis is/are correct?
1 ATPcan be synthesized through substrate level phosphorylation, photophosphorylation and oxidative phosphorylation.
2 The proton-motive force is the establishment of proton gradients and electrochemical potentials across the inner membrane.
3 Proton-motive force is essential for back flow of${{\text{H}}^{+}}$ from outer chamber of matrix of mitochondria through proton channel $\left( {{F}_{0}} \right)$ of ${{F}_{0}}-{{F}_{1}}$ particle to produce ATP.
4 All of the above
Explanation:
(d) The enzyme responsible for oxidative phosphorylation is ATP synthase. ATP synthase is located in the ${{F}_{1}}$ component of ${{F}_{0}}-{{F}_{1}}$ or elementary particles. ATP synthase becomes active in ATP formation only where there is a proton gradient having higher concentration of ${{\text{H}}^{+}}$or protons on the ${{\text{F}}_{0}}$ side as compared to ${{F}_{1}}$ side. Increased proton concentration is produced in the outer chamber of outer surface of inner mitochondrial membrane by pushing of protons with the help of energy liberated by passage of electrons from one carrier to another.
