Lesson 6 - Life processes-Class 10 Science Notes
Life Processes Life Process Those processes of the body which are necessary to prevent damage and break down and which together perform maintenance job are called life processes. Example:- growth, excretion, respiration, circulation, digestion, etc. Bio-chemical process For this life process organisms get complex material form outer energy sources and decomposition and formation take place inside the body. By which these are form to maintain and to growth of body. For this there happen a large series of chemical reactions. These are known as bio-chemical process. There is bio-chemical process called metabolism which takes place in the cells. These cellular process need oxygen to perform this which is obtained from external environment. Common chemical methods for decomposing of molecules Metabolism:- The decomposing of various molecules in the body are taken place by a chemical process is called metabolism. Metabolisms are a bio-chemical process which occur in all living organisms...
