what is anaerobic respiration class 10

Aerobic means “with air”. That is why a hot shower after heavy sports relieve the cramps as it improves blood circulation in the body, which in turn enhances the supply of oxygen to the cells. During aerobic respiration, complete oxidation of carbohydrates takes place.

Respiration is a process in which glucose is broken down with the help of oxygen and energy is released along with the production of carbon dioxide and water. Lower organisms such as bacteria and yeast use this type. Some bacteria, have evolved this kind of system where it utilizes oxygen-containing salts, rather using free oxygen as the electron acceptor. Aerobic and Anaerobic Respiration | Life Processes - YouTube Anaerobic respiration is the culprit to be blamed. Anaerobic respiration is a relatively fast reaction and produces 2 ATP, which is much less than aerobic process. Glucose (a 6-carbon molecule) breaks into pyruvate (a 3-carbon molecule) and pyruvate is then converted to lactic acid (a 3-carbon molecule) along with the release of energy. Depending on whether the respiration is aerobic or anaerobic, the NADH can oxidise to NAD + and be utilised in glycolysis again. Required fields are marked *. But the supply of oxygen to produce the energy is limited. In yeast cells, glucose (a 6-carbon molecule) breaks into pyruvate (a 3-carbon molecule) and pyruvate is then converted to ethanol(a 2-carbon molecule) and carbon dioxide. Class 7 Biology Respiration in Organisms Aerobic respiration In this type of respiration the breathed in oxygen is sent to the entire body and to the cells where the food is broken down into carbon dioxide, water and energy in the presence of oxygen. The product of glycolysis is pyruvate that used in anaerobic respiration … Partial breakdown of glucose, due to lack of oxygen, produces lactic acid and the accumulation of lactic acid causes muscle cramps. This is disproven by the fact that our muscles, during vigorous exercises, undergo anaerobic respiration, where lactic acid is produced as the waste-byproduct instead of carbon dioxide. In other organisms, it occurs during heavy activities. The by-product of this process produces carbon dioxide along with ATP – the energy currency of the cells. To learn more about aerobic and anaerobic respiration, or any other related topic, explore BYJU’S Biology. Therefore, this type of cellular respiration does not use oxygen to produce energy. The equation for aerobic cellular respiration is: There are two main types of anaerobic respiration: The three stages of Aerobic Cellular Respiration are: In the cell, Aerobic respiration occurs within the mitochondria of a cell, and the anaerobic respiration occurs within the cytoplasm of a cell. 10 What are the adaptations in plant leaves to satisfy the oxygen requirement for aerobic respiration? Q41. Glucose --> pyruvate + energy --> ethanol + carbon dioxide + energy. Aerobic respiration- the process of respiration that takes place in the presence of oxygen. Sometimes there is not enough oxygen around for some organisms to respire, but they still need the energy to survive. Under such a condition value of R.Q. During night, in the absence of sunlight photosynthesis do not take place and hence carbon dioxide is released but not used up by the plants. Your email address will not be published. Anaerobic respiration produces a relatively lesser amount of energy as compared to aerobic respiration, as glucose is not completely broken down in the absence of oxygen. Passages are there in the body which takes the oxygen rich air to the area of respiration. Glucose breaks down into carbon dioxide and water. 11. ATP is made from ADP and inorganic phosphate with the help of energy released during respiration. Sol: Respiration is the process which involves exchange of oxygen and carbon dioxide between the organism and the environment. Respiration is the process by which chemical energy The process can be conveniently divided into two categories based on the usage of oxygen, namely aerobic and anaerobic respiration. Aerobic respiration. Filed Under: Class 10, Life processes Tagged With: aerobic respiration, anaerobic respiration, glycolysis, kreb's cycle, respiration About Mrs Shilpi Nagpal Author of this website, Mrs Shilpi Nagpal is MSc (Hons, Chemistry) and BSc (Hons, Chemistry) from Delhi University, B.Ed (I. P. University) and has many years of experience in teaching. Aerobic Respiration — Takes place in the presence of oxygen. The breathing rate, however, may differ under different conditions. Sometimes when we do heavy exercise, anaerobic respiration takes place in our muscle cells.
