Question

which of the following molecules are products of the light reactions of photosynthesis that are utilized in the calvin cycle? co₂ and glucose h₂o and o₂ adp, 81, and nadp+ electrons and h+ atp and nadph

Explanation:

• In the light reactions of photosynthesis, light energy is used to produce ATP (adenosine triphosphate) through photophosphorylation and NADPH (nicotinamide adenine dinucleotide phosphate - hydrogen) through the electron transport chain.
• The Calvin cycle (dark reactions) uses ATP as an energy source and NADPH as a reducing agent.
• \(CO_2\) is taken up from the atmosphere for the Calvin cycle, and glucose is a product of the Calvin cycle. \(H_2O\) is a reactant in the light reactions (split to release \(O_2\)). ADP, \(P_i\), and \(NADP^+\) are reactants in the light reactions (regenerated from ATP and NADPH). Electrons and \(H^+\) are involved in the electron transport chain but are not the final products utilized in the Calvin cycle in the form presented in that option.

Answer:

ATP and NADPH.
