Which of the following statements correctly summarizes a redox reaction that occurs in photosynthesis? A)Glucose is oxidized to form CO_2. B)CO₂ is oxidized to form glucose. C)CO₂ is reduced to form glucose. D)Water is reduced to form O_2. E)O₂ is oxidized to form water.

Question

Quizplus · Accepted Answer

In photosynthesis, the process of CO2 being reduced to form a carbohydrate (glucose) involves a redox reaction in which the CO2 is reduced and gains electrons, while another species is oxidized and loses electrons. In this case, the CO2 is being reduced to form glucose, which means that another species must be oxidized. The species being oxidized is typically water, which loses electrons and is therefore oxidized to form oxygen gas. Therefore, the correct statement would be that CO2 is reduced to form glucose, and water is oxidized to form oxygen gas. Option C states that CO2 is reduced to form glucose, which is correct.
