When the light-harvesting complex absorbs light energy, it is eventually passed

Question

When the light-harvesting complex absorbs light energy, it is eventually passed to P680 which emits an electron. Which of the following statements correctly describes the energy and electrons during this process? When P680 loses an electron, it becomes positively charged and has less energy than it did before losing the electron.

P680 donates the electron to P700 forming ATP and water in the process.

Water donates electrons to the light harvesting complex, providing the electrons that P680 will pass on to P700.

P680+ has less energy.

Electrons are passed from the light harvesting complex to water forming oxygen

Explanation / Answer

Answer is .......

Water donates electrons to the light harvesting complex, providing the electrons that P680 will pass on to P700
