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.

Answer:
We all know that living beings are bio-chemical organisms. They are made up of chemicals. A number of metabolic activities are taking place inside of us at all times. Metabolism is defined as the sum total of all chemical reactions that take place inside the body. Metabolism is purely characteristic of living beings. No living organism can exhibit metabolism.However, these reactions can be replicated outside a living body i.e. in a cell free system. But that doesn’t make them living. The reactions do not lead to generation of life or maintenance of life hence cannot be called living.....
Explanation:
♥ All living organisms are made up of chemicals
♥ There are thousands of metabolic reactions occurring simultaneously inside all living organisms, be they are unicellular or multicellular. The sum total of all the chemical reactions occurring in our body is metabolism. All plants, animals, fungi and microbes exhibit metabolism.
♥ No non-living objects exhibit metabolism. Metabolic reactions can be demonstrated outside the body in cell free system. An isolated metabolic reaction outside the body of an organism, performed in a test tube is neither living nor non-living. ‘
♥Hence, while metabolism is a defining feature of all living organisms without exception, isolated metabolic reactions in vitro are not living things but surely living reactions.
