-Which of the following BEST describes the direct mechanism of ATP production during photosynthesis?

• A)use of the energy generated as hydrogen ions (H⁺)move up a proton gradient; this energy is used to make ATP
• B)use of the energy released as excited electrons are passed from one molecule to another in the electron transport system; the energy is converted to the chemical bond energy of ATP
• C)use of the energy stored in excited electrons; as the electrons move from the excited state to the ground state,the energy released is converted to the energy stored in the third phosphate bond in ATP
• D)use of the energy stored in hydrogen ion (H⁺)gradients; the potential energy of the proton gradient is released as the protons move down their gradient through special membrane protein channels; this energy is converted to chemical bond energy in the ATP molecule
