A simplified version of photosynthesis can be represented as carbon dioxide combining with water to form glucose and oxygen: 6CO2 + 6H20 - C6H12O6 +
602. In this reaction, is oxidized.
A) hydrogen
B)
oxygen
C) carbon dioxide
D) carbon

B) oxygen is oxidized.

Given

photosynthesis reaction

6CO2 + 6H20 ⇒ C6H12O6 + 602

Required

the oxidation compound

Solution

Oxidation-reduction reactions or abbreviated as Redox are chemical reactions in which there is a change in oxidation number

Oxidation is an increase in oxidation number, whereas Reduction is a decrease in oxidation number.

In the photosynthetic reaction, oxidation and reduction reactions occur in:

CO2 to C6H12O6 : reduction

Oxidation number of C from +4 to 0

H2O to O2 : oxidation

Oxidation number of O from -2 to 0
