Question

what are the two products of the light reactions that are needed for the calvin cycle?
nadp + and glucose
nadph and atp
nad and nadph
oxygen and nadph

Explanation:

The light reactions of photosynthesis produce ATP (energy carrier) and NADPH (electron carrier/reducing agent). These two molecules are essential for the Calvin cycle to convert CO₂ into glucose, as the cycle requires energy (from ATP) and electrons (from NADPH) for carbon fixation and sugar synthesis. The other options are incorrect: NADP⁺ is a reactant, glucose is a Calvin cycle product, NAD is unrelated to photosynthesis here, and oxygen is a byproduct of light reactions not used in the Calvin cycle.

Answer:

NADPH and ATP
