Respiratory system

On an a living organisms need air for respiration, as it contains oygen. We breathe out carbon dioxide rich air and inhale oxygen .  which is transported to all parts of body an cell (via haemoglobin). In the cells, oxygen helps in th breakdown of food and to obtain energy d each . Lungs Cellular Respiration " The process of breakdown of food in the cell with the surrour chest c release of energy is called cellular respiration. Cellul respiration takes place in mitochondria and cytoplasm o the cells of all the organisms. The ga alveoli heart t e pe and ex ar n this process, the food (glucose) is broken down into carbon dioxide and water using oxygen. C6H1206 + 602-6 co2 + 6H20 + Energy with the use of oxygen it is called aerobic respiration. occurs without using oxygen, this is called anaerobic o Respiration is of two types 1. Aerobic Respiration The breakdown of glucose occurs . Smok 2. Anaerobie Respiration The breakdown of glucose may c Mour than + Energy Breat respiration, e.g. Glucose Absence of O2 Alcohol+ Carbon dioxide It has three main stages (i) Glycolysis (cytoplasm) (i) Citric acid cycle [Kreb's cycle (mitochondria)) (ii) Electron transport (inner membrane of mitochondria) Earthwe Cockroa bod netw becat gase .Yeasts are single-celled organisms. They respire anaerobically and during this process yield alcohol. They are used to make wine and beer Fro . The accumulation of lactic acid causes pain and fatigue in and Fishes I the muscles. During heavy exercise, fast running, cycling walking for many hours or heavy weight lifting, the demand of energy is high. So, during this partial breakdown of glucose produce lactic acid.
