In photosynthesis, energy for attaching phosphate to ADP in photosystem II comes from
1 Oxidation of glucose
2 Sunlight directly
3 A proton gradient
4 Substrate-level phosphorylation
Explanation:
A proton gradient is created between the stroma of chloroplast and lumen of thylakoid. ATP synthase has a channel that allows diffusion of protons back across the membrane; this releases enough energy to activate ATP synthase enzyme that catalyses the formation of ATP

During photosynthesis the protons are transported across the thylakoid membrane into the lumen because
1 Electrons are transfered to hydrogen carrier, which is present on the outer side of membrane
2 Electrons are transferred to electron carrier
3 Electrons are transferred to intermembrane space
4 Electrons are transferred to hydrogen carrier which is present on inner membrane
Explanation:
During ETS, electron and proton exchange across the membranes takes place simultaneously. The protons are transported across the thylakoid membrane into the lumen because electrons are transfered to hydrogen carrier, which is present on the outer side of membrane.

ATPase has
1 Channel that allows \({H^ + }\) diffusion
2 Channel that allows electron diffusion
3 Channel that allows \({O_2}\) molecule diffusion
4 None of them
Explanation:
CF0 part of ATP Synthase forms a transmembrane channel that carries out facilitated diffusion of protons (H+) across the thylakoid membrane.
