Question

Which of the following statements best explains how the energy in a photon of light is stored in a molecule of

Answer 1

Answer:

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

Explanation:

Photosynthesis is a metabolic process carried out by the cells of autotrophic organisms. The process involves synthesis of food (glucose) using light energy. Photosynthesis involves two processes viz: light-dependent stage and light-independent stage.

The light dependent stage of photosynthesis occurs in the thylakoid membrane of the CHLOROPLAST, where Chlorophyll pigments capture photons of light from the sun. The Chlorophyll becomes activated and provides energy to build a proton pump, which eventually powers the synthesis of ATP and NADPH molecules.

The ATP and NADPH molecules enter into the stroma of the CHLOROPLAST, where the light-independent or Calvin cycle takes place. In the Calvin cycle, ATP provides energy while NADPH supplies electrons that produce Glyceraldehyde-3-phosphate (G3P) molecules.
