FADH2
B
Glucose
C
NADPH
D
ATP
Verified step by step guidance
1
Understand the context: The light reactions are part of photosynthesis, occurring in the thylakoid membranes of chloroplasts, where light energy is converted into chemical energy.
Identify the main products of the light reactions: The light reactions produce ATP and NADPH, which are used in the Calvin cycle to synthesize glucose.
Differentiate between the molecules: FADH2 is primarily involved in cellular respiration, not photosynthesis. Glucose is a product of the Calvin cycle, not the light reactions.
Focus on the role of ATP: ATP (adenosine triphosphate) is a key energy carrier molecule produced during the light reactions and is used to power various processes in the Calvin cycle.
Conclude with the correct molecule: Based on the roles and processes involved, ATP is the energy molecule produced during the light reactions that helps to power the Calvin cycle.
