Electron Transport Chains | MCQs

Explanation

During light reactions, PS II receives electrons from the splitting of water.

This process, known as photolysis, generates oxygen, protons, and electrons.

It replenishing the electron supply in Photosystem II.

Explanation

In the journey of electrons from photosystem II to photosystem I, plastocyanin is reduced by the cytochrome complex.

The cytochrome complex facilitates the transfer of electrons to plastocyanin, which then carries them to Photosystem I.
