Question

the less energy containing compounds created in the light - dependent reactions that are used in the light - independent reactions are ___ and ___.
a adp and nadp+
b nadph and atp
c water and glucose
d pyruvic acid and atp synthase

Explanation:

In photosynthesis, light - dependent reactions produce energy - rich compounds (NADPH and ATP) that are used in light - independent (Calvin cycle) reactions to fix carbon and make glucose. Option A: ADP is a low - energy form, and NADP⁺ is the oxidized form, not the products of light - dependent reactions used in light - independent. Option C: Water is a reactant in light - dependent reactions, and glucose is a product of light - independent. Option D: Pyruvic acid is related to cellular respiration, and ATP synthase is an enzyme, not compounds used in light - independent reactions from light - dependent.

Answer:

B. NADPH and ATP
