Question

How many statement are true for photosynthesis:
(A) $C{O}_2$ is oxidize and $H_{2}O$ is reduced
(B) $C{O}_2$ is reduced and $H_{2}O$ is oxidize
(C) $C{O}_2$ is reduced to from glucose
(D) $H_{2}O$ is oxidized to evolve $O_2$

• A. One
• B. Two
• C. Three
• D. Four

Answer 1

The correct option is C Three

In photosynthesis:

• Water is oxidized in photosynthesis, which means it loses electrons, and carbon dioxide is reduced, meaning it gains electrons.
  
• The oxidation-reduction action of photosynthesis transforms batches of six water molecules, H2O, and six carbon dioxide molecules, CO2, into one glucose molecule, C6H1206, and six molecules of O2, which is breathable oxygen.

So, the correct answer is 'Three'.
