Light Dependent Reaction of Photosynthesis

Light Independent Reaction(Overview):

Light strikes a chlorophyll molecule, resulting in a process known as photoionisation

Two electrons leave the chlorophyll molecule and pass to an electron carrier

Electrons are transferred along a series of electron carriers, forming an electron transfer chain (ETC) within the thylakoid membrane

Electrons lose energy as they are passed from one electron carrier to the next.

This energy is actively transporting protons from the stroma into the thylakoid space, forming an electrochemical gradient across the membrane.
