What is the correct sequence of the seven events in the light reactions of photosynthesis?
1-ATP Synthase produces ATP
2-H₂O is split producing electrons to reduce P₆₈₀
3-the electron transport chain produces a H⁺ ion gradient
4-production of NADPH
5-P₆₈₀ reaction center is oxidized when an excited electron is ejected
6- P₇₀₀ is reduced by an electron from P₆₈₀
7-absorbsion of a photon in pigments of photosystem II

Question

Quizplus · Accepted Answer

The correct sequence starts with the absorption of a photon by pigments in photosystem II (7), followed by the oxidation of the reaction center in photosystem II as an excited electron is ejected (5). Water is then split to replace the lost electron, producing electrons, protons, and oxygen (2). The electron transport chain uses these electrons to create a proton gradient across the thylakoid membrane (3), which drives the synthesis of ATP. Meanwhile, the electron from photosystem II reduces photosystem I (6), leading to the production of NADPH (4), and finally, ATP synthase uses the proton gradient to produce ATP (1).
