Detailed explanation-1: -Answer and Explanation: In photosynthesis, electrons are supplied to the reaction center via the splitting of water, which yields O2 as a byproduct. This statement is true.
Detailed explanation-2: -NADPH and ATP are used. Oxygen gas is released. Water is split.
Detailed explanation-3: -Calvin Cycle : Example Question #3 Which of the following is not true of the Calvin cycle? Explanation: Despite the Calvin cycle’s other name (light independent reactions), light is indirectly required for this process to function. All other choices are true of the Calvin cycle.
Detailed explanation-4: -During photosynthesis, water is oxidized to release oxygen and carbon dioxide is reduced to form sugar. Thus twelve molecules of water are oxidised to release six molecules of oxygen released along with the formation of one molecule of hexose by six turns of Calvin cycle.
Detailed explanation-5: -TRUE 3. Electrons from water molecules replace the ones lost by photosystem II.
