Cellular respiration is our body's process to release energy from the food we eat. Glucose from food is broken down to produce ATP, which powers our cells.
The relationship of the law of thermal dynamics to cellular respiration is the first law of thermodynamics which states that energy cannot be made or destroyed. Energy can only be transferred from one form to another.
The second law of thermodynamics states that the entropy of any isolated system always increases. Entropy is constant change. It can be related to cellular respiration when glucose is changed to another form when it is broken down to pyruvate.
In conclusion, the energy stored inside our food is transferred to making ATP inside our cells.
