Hello guys welcome to my YouTube channel here We will discuss about respiration in Life Processes Respiration is a fundamental life process that occurs in living organisms to produce energy from the breakdown of organic molecules, particularly glucose. It is a complex biochemical process that involves the exchange of gases, typically oxygen (O2) and carbon dioxide (CO2), between the organism and its environment. There are two main types of respiration: aerobic respiration and anaerobic respiration. 1. Aerobic Respiration: Aerobic respiration is the most common form of respiration, and it requires oxygen to occur. It takes place in the cells of most living organisms, including plants, animals, and fungi. The process can be summarized by the following equation: C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 (carbon dioxide) + 6H2O (water) + Energy (ATP) In this process, glucose and oxygen are combined in the presence of enzymes within the cell's mitochondria to produce carbon dioxide, water, and a significant amount of adenosine triphosphate (ATP). ATP is the primary energy currency in cells, and it is utilized for various cellular activities. 2. Anaerobic Respiration: Anaerobic respiration occurs in the absence of oxygen or when oxygen availability is limited. This type of respiration is less efficient than aerobic respiration because it yields less ATP from the breakdown of glucose. Anaerobic respiration occurs in certain microorganisms, some plants, and animal cells during strenuous exercise when the oxygen supply cannot meet the demand. There are two main types of anaerobic respiration: a. Alcoholic Fermentation: In this type of anaerobic respiration, glucose is broken down into ethanol (alcohol), carbon dioxide, and a small amount of ATP. This process is carried out by some bacteria and yeast during processes like brewing, winemaking, and bread-making. b. Lactic Acid Fermentation: In lactic acid fermentation, glucose is converted into lactic acid and a small amount of ATP. This process occurs in animal cells, including human muscle cells, when the oxygen supply is insufficient to meet the energy demands. It is responsible for the buildup of lactic acid, leading to muscle fatigue and soreness during intense physical activity. Overall, respiration is vital for living organisms as it provides the energy needed for growth, movement, reproduction, and other life processes. It is essential to maintain a proper balance of aerobic and anaerobic respiration based on the organism's energy requirements and environmental conditions. #biology #knowledge #deeba #humandigestivesystem #dna #respiration #sciencebydeeba
