Metabolism is a defining feature of all living organisms without exception.

Isolated metabolic reactions in vitro are not living things but surely livingreactions. Comment.

Metabolism is defined as the sum total of all chemical reactions occurring in the body of all living organism be it at a plant or an animal, fungi or microbe, exhibit metabolism. An Isolated metabolism reaction occur in-vitro as it includes the same environment required to carry out reaction within a cell. Here the reaction can also be carried out outside the body in a cell free system and includes building cell components, taking up of raw material and converting into the energy that is available with the molecule and finally releasing the end product. Hence, it shows that in-vitro reactions represent non living things but living reactions.
