Question

The chemical equation below summarizes cellular respiration. 6O2 + C6H12O6 à 6CO2 + 6H2O + energy The energy that is released by cellular respiration is in the form of dark energy. solar energy. nuclear energy. chemical energy.

Answer 1

Answer : Option D) Chemical energy.

Explanation : The chemical equation $6 O_{2} + C_{6}H_{12}O_{6} ----> 6 CO_{2} + 6H_{2}O + Energy$

In this reaction it is clear that 6 molecules of oxygen when combines with one molecule of glucose it produces 6 molecules of carbon dioxide and 6 molecules of water along with the generation of energy.

This is a pure chemical energy transformation reaction, as from the chemicals the energy is getting generated. Therefore, It is oxygen and glucose which helps in generating the energy.

So, the energy that is released by cellular respiration is in the form of chemical energy.

Answer 2

Chemical energy is released from the breaking down of glucose.
