The first law of thermodynamics: Energy can neither be created or destroyed.
This law is obeyed by the metabolism process since the carbohydrates consumed have not been lost but absorbed by the body as a source of energy or heat.
The second law of thermodynamics: All spontaneous events are increasing the total entropy in the system.
The second law has applied to the process of metabolism by which the carbohydrates have changed its original states as the progress carries on, in which it has created entropy.
The third law of thermodynamics: Absolute zero is removal of all movements.
First of all, with respect to recent science researching we have not yet reached to the point where absolute zero is at. Secondly, human is not able to survive at such temperature.
Specifically to the second law of thermodynamics with respect to the metabolism process. The second law has stated that the entropy increases over time. Since all biological organism are undergoing exergonic processes to maintain the internal order. All exergonic processes are spontaneous and are creating entropy in which negative energy are produced from the activation energy used. More energy available for use after the process. However, with respect to the first law of energy, the energy are conserved within the process in a form of heat. Also the randomness created by the metabolism can be proven by the biological process such as photosynthesis or cellular respiration. Where final products are in different states or energy forms from the initial inputs. ( photosynthesis uses heat as initial input, and produced ATP as the final products.) Therefore, as conclusion, the metabolism has obeyed the second law of thermodynamics in which randomness has been created.
