The correct answer is: It is used to produce glucose molecules.
During photosynthesis, light energy is captured by chlorophyll in the chloroplasts of plant cells and is used to convert carbon dioxide and water into glucose (a type of sugar). This process is essential for plants to create their own food, which can then be used for energy and growth. While ATP (adenosine triphosphate) is also produced during photosynthesis and serves as an energy carrier, the primary outcome of capturing light energy in this process is the production of glucose.
