What are the two main chemical energy products of the light reactions that are essential for the Calvin cycle?

  • A: O2 and H2O
  • B: ATP and NADPH
  • C: CO2 and sugar
  • D: NADP+ and ADP

Explanation

The text explicitly states: 'light energy is initially converted to chemical energy in the form of two compounds: NADPH and ATP.' It further explains that 'it is the Calvin cycle that makes sugar, but it can do so only with the help of the NADPH and ATP produced by the light reactions.'
