Solution
The process described in the question is known as the Linear Electron Flow.
Here's a step-by-step explanation:
-
The process begins in Photosystem II when photons hit the chlorophyll molecules.
-
The energy from the light excites an electron from the chlorophyll molecule, causing it to be 'boosted' to a higher energy level and transferred to the primary electron acceptor.
-
The 'hole' left by the excited electron in the chlorophyll molecule is filled by taking an electron from a water molecule, splitting it into 2H+ + 1/2O2.
-
The excited electron then moves down an Electron Transport Chain, losing energy as it goes. This energy is used to pump hydrogen ions across the thylakoid membrane, creating a concentration gradient.
-
The electron then enters Photosystem I, where it is again excited by light energy and transferred to another primary electron acceptor.
-
From there, the
