Which is not true for the dark reaction?

Explanation

The correct answer is that the dark reaction is not called the Z-scheme. The Z-scheme specifically refers to the series of electron transport processes that occur in the light-dependent reactions of photosynthesis, where electrons move in a zigzag pattern. The dark reaction, also known as the Calvin cycle, does not involve this electron transport chain and instead focuses on carbon fixation, using ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into G3P, a precursor to glucose. Options A, B, and D correctly describe processes involved in the dark reaction.
