Question

Which of the following is NOT a step in the light-dependent reactions?

Answer 1

Answer: ATP and NADPH are used to produce high energy sugars

Explanation:

Photosynthesis is composed of a light phase and a dark or biosynthetic phase. In the light phase the energy of light is transformed into chemical energy. The ATP and NADPH produced in the light phase are then used in the dark phase (not dependent on light) to synthesize organic matter (like carbohydrates or sugars, amino acids) from inorganic compounds (CO2, nitrates and nitrites and sulfates).

Answer 2

The answer would be D. 

I hope this helps. 
 
 The Calvin cycle uses carbon dioxide molecules as well as ATP and NADPH from the light-dependent reactions to make sugars. The reactions of the Calvin cycle useATP and NADPH as energy sources. They do not directly require light.
