WebOct 23, 2024 · Photolysis: The light reaction initiates when the chlorophyll absorbs light. It causes one of its electrons to move to a higher energy state. The excited electron is transferred to an acceptor molecule and is replaced by an electron from water (H 2 O). It causes the decomposition of water into H + and OH –, hence termed as photolysis. WebDec 2, 2015 · In photolysis (e.g. splitting water) you get the energy from the absorbed photons. The exact process is called the Joliot-Kok cycle: Figure 1 - Joliot-Kok cycle - … WebThe high-energy electron is passed to an acceptor molecule and replaced with an electron from water. This splitting of water releases the O 2 \text O_2 O 2 ... photolysis and NADP reduction occur on opposite sides of the thylakoid membrane, photolysis contributes to the proton gradient, and that the uptake of hydrogen ions to form NADPH occurs ... how to delete blank cells in google sheets
