Question

(04.04 MC) Which of the following substances is released during the light-dependent reactions of photosynthesis? (4 points) Carbon dioxide Oxygen Water Glucose

Answer 1

Step-by-step explanation:

The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

Answer 2

Light Reactions transform energy from sunlight into chemical energy, and produce and release oxygen gas. Light also provides energy to split water molecules into electrons, hydrogen ions, and oxygen gas. The oxygen gas is released as “waste”, but it is the source of the oxygen in Earth's atmosphere.
