In photosynthesis, which molecule is being oxidized and which is being reduced?

Question

6CO2 + 6H2O~~> C6 H12 O6 + 6O2

Answer 1

6CO2 + 6H2O → 6(CH2O) + 6O2

Oxidation is Loss of electrons

Reduction is Gain of electrons

acronym to help you remember: OIL RIG

Oxidation

1. During photosynthesis, water gets oxidized to oxygen (O2).
2. 6H2O → 3O2 + 12[H]

Reduction

1. 12[H] + 6CO2 → 6(CH2O)
2. In photosynthesis, CO2 gets reduced to carbohydrates.
