Question

1. which of the following statements best explains how the energy in a photon of light is stored in a molecule of the sugar g3p? a. light energy directly provides energy to rubp and co₂, which produce g3p in the calvin cycle. b. light energy directly provides energy to atp synthase, which produces atp during the light reactions. c. light energy energizes electrons to make atp and nadph, which provide energy to produce g3p in the calvin cycle.

Explanation:

In photosynthesis, light - energy is used in the light - reactions to energize electrons. This energy is then used to produce ATP and NADPH. These energy - carriers (ATP and NADPH) are used in the Calvin cycle to produce G3P. Option a is incorrect as light energy doesn't directly provide energy to RuBP and CO₂. Option b is wrong because light energy doesn't directly provide energy to ATP synthase to produce G3P.

Answer:

C. Light energy energizes electrons to make ATP and NADPH, which provide energy to produce G3P in the Calvin cycle.
