What is the primary product of the light-dependent reactions of photosynthesis that is then used in the Calvin cycle?

A) Glucose
B) Oxygen
C) ATP and NADPH
D) Carbon Dioxide

Explanation

The light-dependent reactions convert light energy into chemical energy in the form of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate), which are then utilized in the light-independent Calvin cycle to synthesize glucose from carbon dioxide.
