Question

Create the overall reaction for glucose breakdown in the standard order found in your text using the following reactants and products and label the portion of the equation that is oxidation and the portion that is reduction, thus indicating a redox reaction.

- energy
- oxidation
- reduction
- 6CO2
- 6O2
-6H2O
-C6H12O6

Answer 1

Answer : The balanced chemical reaction will be,

`C_6H_(12)O_6+6O_2\rightarrow 6CO_2+6H_2O+Energy`

Explanation :

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.

Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.

Glucose on oxidation gives carbon dioxide and water as a product and some amount of energy is also released.

The balanced chemical reaction will be,

`C_6H_(12)O_6+6O_2\rightarrow 6CO_2+6H_2O+Energy`

In this reaction, glucose molecule shows oxidation due to change in oxidation state of carbon from (0) to (+4) and oxygen molecule shows reduction due to change in oxidation state of oxygen from (0) to (-2).
