Question

Why is energy from light required for water to serve as an electron donor? a. Hydrogen bonding among water molecules interferes with electron donation until the molecules are excited by light. b. Excitation of water molecules by light is required for there to be sufficient diffusion all the way into the thylakoid lumen c. Oxygen readily accepts electrons and therefore requires a large energy input before donating electrons. d. Water has very little intrinsic energy until it accepts energy from a photon
