Explain the three pathways of breakdown of glucose in living organisms ?? |
|
Answer» The process of taking in\xa0oxygen\xa0and to use it in the process of\xa0break - down\xa0of food for\xa0cellular\xa0needs is called as\xa0respiration.There\'re\xa0three\xa0pathways of breakdown of glucose in living organisms. They\'re as follows:(i) Aerobic respiration:The process of\xa0breaking down\xa0of food in the\xa0presence\xa0of oxygen to form energy is called as\xa0aerobic respiration.The\xa06 - carbon molecule, glucose is broken down into a\xa03 - carbon molecule,\xa0pyruvate. This all happens in the presence of\xa0oxygen. They by - products are\xa0Carbon dioxide,\xa0Water\xa0and\xa0Energy.(ii) Anaerobic respiration: The process of breaking down of food in the\xa0absence\xa0of oxygen to form energy is called as\xa0anaerobic respiration.During\xa0heavy exercise, our body needs more energy to continue our exercise. Here, the more\xa0oxygen\xa0is needed. But the oxygen taken by nose is\xa0insufficient.\xa0And there\'s no time to break down food in the presence of oxygen \'cause of lacking of oxygen.So, the energy produced in\xa0mitochondria\xa0in the absence of oxygen produce\xa0lactic\xa0acid\xa0which causes muscle cramps.The pyruvate is again broken down into Lactic acid which\'s also a\xa0three - carbon molecule.(iii) In mitocondria: The break down of pyruvate using oxygen takes place in\xa0mitochondria.Pyruvate is broken down to give a\xa0three - carbon molecules\xa0of\xa0Carbon dioxide.
