Metabolism is a defining feature of all living


Metabolism is a defining feature of all living organisms without exception. Isolated metabolic reactions in vitro are not living things but surely living reactions. Comment.


Metabolism is defined as the total of all chemical reactions that take place inside the body. Metabolism is purely characteristic of living beings. No living organism can

exhibit metabolism. In a cell-free system, these reactions can be replicated that is outside a living body.

These reactions never lead to a new life or maintenance of life. Therefore it can’t be called living.
