Question

photosynthesis ______. true. does not use chemiosmosis process. false. involves reduction of nadph into nadp⁺ during dark reaction. true. delivers high - energy electron - carrying molecules to the calvin cycle. false. creates proton gradient by pumping the hydrogen molecules out of the thylakoid lumen.

Explanation:

1. Analyze Option 1: Photosynthesis (light - dependent reactions) does use chemiosmosis to generate ATP, so "True. Does not use chemiosmosis process" is wrong.
2. Analyze Option 2: In the dark reaction (Calvin cycle), NADPH is oxidized (loses electrons) to \(NADP^{+}\), not reduced. So the statement "False. Involves reduction of NADPH into \(NADP^{+}\) during dark reaction" has the wrong description of the reaction (it's oxidation, not reduction), but the "False" part is correct in terms of the reaction type, but the reasoning is incorrect. However, we will check other options.
3. Analyze Option 3: During photosynthesis, the light - dependent reactions produce ATP and NADPH (high - energy electron - carrying molecules). These molecules are then delivered to the Calvin cycle (dark reaction) to be used in the synthesis of carbohydrates. So this statement is true.
4. Analyze Option 4: In the light - dependent reactions of photosynthesis, protons (\(H^{+}\)) are pumped into the thylakoid lumen, creating a proton gradient across the thylakoid membrane, not out of the thylakoid lumen. So the statement "False. Creates proton gradient by pumping the hydrogen molecules out of the thylakoid lumen" is wrong.

Answer:

True. Delivers high - energy electron - carrying molecules to the Calvin cycle
