Question

Sequence of steps involved in light reaction

Answer 1

1 as light energy is absorbed It excited the electrons in clorophyll a, chlorophyll b, and cartenoids electrons pass through the pigments by jumping along the photosystems in light reactions

.

step 2 That high-energy e- finally reaches a molecule of chlorophyll a that will pass it along to the PEA molecules in the thylakoid membrane in light reactions

.

step 3 The e- energy moves through the electron transport chain (ETC) proteins located along the thylakoid membrane in light reactions

...

step 4a The e- from PS II that moved down that portion of the ETC have replenished the e- that left PS I in light reactions

...

step 4b water spliting occurs here in calvin cycle in light reactions

...

step 5 All of these less energetic e- that moved down the ETC from PS I are paired with a H+ in the stroma to form H (hydrogen atom) in light reactions

...

step 6 : The H+ within in the thylakoid space create a high concentration gradient compared to the low concentration of H+ in the stroma in light reactions

Answer 2

Answer:

Here are the basic steps: Light absorption in PSII. When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. There, energy is transferred to P680, boosting an electron to a high energy level.
