Q. Photophosphorylation in chloroplast is most similar to the
A) Mitochondrial substrate level phosphorylation
B) Mitochondrial oxidative phosphorylation
C) Mitochondrial hydrolysis of $H_{2}O$
D) All of the above
Explanation
Photophosphorylation in chloroplast is similar to the mitochondrial oxidative phosphorylation. In both of them, the proton gradient plays a significant role in chloroplast the proton gradient develops in the lumen and in mitochondria the proton gradient develops in the intermitochondrial space. Rest of the mechanism of phosphorylation remains the same in both the organelle
