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.
All living organisms are made of chemicals which belong to various classes and have different sizes and functions. In the cells, these chemicals are constantly being made and changed into some other biomolecules. These conversions or chemical reactions taking place in the body are collectively known as metabolism. All plants, animals, fungi and microbes exhibit metabolism. Non-living objects do not exhibit metabolism. So we can say metabolism is a defining feature of all living organisms without exception.
Metabolic reactions can be demonstrated outside the body in a test-tube. A metabolic reaction preformed in a test-tube (in vitro) is neither living nor non-living but surely living reaction.
Thank you for the answer but may I know the meaning of LIVING REACTION
METABOLIC REACTIONS or LIVING REACTIONS are those chemical reactions that help us to live like respiratory reactions, digestive reactions etc.
