The PS II, during light reaction,s receives electrons from splitting:
Correct answer: A. Water
- A. Water
- B. Plastoquinone
- C. Plastocyanin
- D. Ferredoxin
Explanation
Water is the true source of electrons for PS II, where photolysis (splitting of water) provides the electrons to start the chain.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
