What roles do electrons and hydrogen ions play in the light- dependent reaction of photosynthesis?

Answer 1

They are pumped across the mitochondrial inner membrane against their concentration gradient (to where their concentration is high); as the H+ ions flow back to where their concentration is low, they drive ATP synthase to form ATP

Answer 2

Electrons excited out of the reaction centre in the photosystems are carried along a chain. The electron transport chain pumps protons, just like the respiratory complexes, and the electrons are eventually dumped onto NADP to form NADPH. Protons flow back through ATP synthase, generating ATP.

Answer 3

The are pumped by electron action into the outer lumen of the mitochondria. There, when they reach a critical concentration, the come down their concentration gradient through the ATP synthase and provide the motive force for ADP being phosphorylated into ATP.

Answer 4

In the light-dependent reaction of photosynthesis, electrons are excited by light energy and carried through the electron transport chain to help create a proton gradient across the thylakoid membrane. Hydrogen ions are pumped across the membrane using energy from these excited electrons, contributing to the formation of ATP through ATP synthase. Both electrons and hydrogen ions are essential for the production of energy-rich molecules like ATP and NADPH in this stage of photosynthesis.
