Transcript text: Multiple Choice Question In the light reactions, pigment molecules in photosystems capture photons of light, and energy from light becomes stored as potential energy in $\qquad$ oxygen and glucose ATP and NADPH NADH and $\mathrm{FADH}_{2}$ ATP and glucose

Solution

The answer is the second one: ATP and NADPH.

Explanation for each option:

Oxygen and glucose: This option is incorrect. Oxygen is a byproduct of the light reactions, and glucose is produced during the Calvin cycle, not directly in the light reactions.
ATP and NADPH: This option is correct. In the light reactions of photosynthesis, energy from light is used to produce ATP and NADPH, which are then used in the Calvin cycle to synthesize glucose.
NADH and FADH₂: This option is incorrect. NADH and FADH₂ are electron carriers involved in cellular respiration, not in the light reactions of photosynthesis.
ATP and glucose: This option is incorrect. While ATP is produced in the light reactions, glucose is not directly produced until the Calvin cycle.

In summary, during the light reactions of photosynthesis, the energy from light is stored as potential energy in the form of ATP and NADPH.
