Which of the following is cycled in the cyclic variation of the light reactions?
A. protons
B. NADPH
C. ribulose bisphosphate
D. ATP
E. electrons

Answer (2)

In the cyclic variation of the light reactions of photosynthesis, the component that is cycled is electrons . These electrons are excited by light and travel through the electron transport chain, creating ATP. This process is essential for the energy needs of the plant, but it does not produce NADPH . ;

In the cyclic variation of the light reactions, electrons are cycled through the process. This occurs when light energy excites electrons in chlorophyll, which then move through the electron transport chain and return to the chlorophyll. This process generates ATP but not NADPH.
