What is the difference between the mitochondria and the excretory system?

Mitochondria is a membrane-bound organelle stored in cells and their function is to generate chemical energy to power the cell's biochemical reaction.

The excretory system is an organ system that eliminates wastes, prevents harmful accumulation of chemicals in the body, and maintains the body's chemical concentration.

Explanation:

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
