Solution
The correct option is B Utilised
During cyclic photophosphorylation only ATP is synthesized, whereas during non-cyclic photophosphorylation both ATP and reduced coenzyme NADPH2 are synthesized. The ATP and NADPH2 synthesized in light reaction (cyclic and non-cyclic photophosphorylation) are used up subsequently in dark reaction to reduce carbon dioxide into sugars. The NADPH2 is used as a reducing agent, hence NADPH2 is called as reducing power, whereas ATP is required in Calvin cycle to reduce carbon dioxide, hence ATP is called as assimilatory power.
