Question

which of the following statements correctly summarizes a redox reaction that occurs in photosynthesis?
glucose is oxidized to form co
co₂ is oxidized to form glucose.
co₂ is reduced to form glucose.
water is reduced to form o
o₂ is oxidized to form water.

Explanation:

In photosynthesis, \(CO_2\) gains electrons (is reduced) to form glucose (\(C_6H_{12}O_6\)). Oxidation involves the loss of electrons, and reduction involves the gain of electrons. Water (\(H_2O\)) is oxidized (loses electrons) to form \(O_2\) during the light - dependent reactions. Glucose oxidation occurs in cellular respiration, not photosynthesis.

Answer:

CO₂ is reduced to form glucose.
