Plants are the primary providers of oxygen,which is obtained by the reduction of carbon dioxide.What chemical donates the electrons needed for CO₂ reduction?

Question

Quizplus · Accepted Answer

Water donates the electrons needed for CO₂ reduction through the process of photosynthesis, specifically during the light-dependent reactions. Sunlight provides the energy for this process, but water is the source of electrons. Glucose is a product of photosynthesis rather than a donor of electrons, while carbon monoxide and oxygen are not involved in photosynthesis at all.
