During photosynthesis in plants and algae, _____ is oxidized and _____ is reduced. A)O₂; CO₂ B)CO₂; H₂O C)H₂O; O₂ D)H₂O; CO₂ E)NADPH; ATP

Question

Quizplus · Accepted Answer

During photosynthesis, water (H2O) is oxidized to produce oxygen (O2) and electrons, which are then used to reduce carbon dioxide (CO2) to form glucose (C6H12O6). Therefore, H2O is oxidized and CO2 is reduced. Choice D lists the correct elements involved in the redox reactions of photosynthesis: H (from H2O) is oxidized and C (from CO2) is reduced. Choices A, B, C, and E list incorrect elements or molecules involved in photosynthesis.
