AnswerVerified516k+ viewsHint: Respiration is one of the most important processes that all living organisms go through in order to survive. When you sprint to catch your school bus, you notice that your respiration quickens. It's because running demands additional energy, which is delivered by respiration. Breathing became faster as a result of this. Breathing is an important aspect of respiration, but it is also a function that keeps our bodies healthy. Simply put, respiration is the process through which the nutrients we consume are transformed into usable energy. The cell, as we all know, is the structural and functional unit of life, and each cell requires energy to function properly. As a result, cellular respiration refers to breathing that occurs at the cellular level, which is the smallest level of our bodies.Complete answer:Cellular respiration is a series of metabolic events that take place inside cells to convert biological energy acquired from food into the chemical molecule adenosine triphosphate (ATP). Metabolism is a series of chemical reactions that occur in order to keep an organism's cells alive.Cellular respiration can be divided into two types: aerobic and anaerobic.Aerobic respiration refers to breathing that occurs in the presence of oxygen.The breakdown of glucose molecules requires oxygen for cellular respiration to produce energy.Oxygen is required for energy production via the electron transport chain, which is an important part of cellular respiration. Cells employ glucose and oxygen to make ATP molecules, which are essential for cellular metabolism to function.In cellular respiration, oxygen acts as a final electron acceptor, aiding the passage of electrons down a chain, resulting in the formation of adenosine triphosphate (ATP). Water is formed when oxygen reacts with electrons and hydrogen ions to form water. As a result, the significance.Note: The three phases of Respiration are:Glycolysis- Glucose molecules are transformed to pyruvic acid, which is then oxidised to carbon dioxide and water, leaving two carbon molecules, acetyl-CoA. Two molecules of ATP and NADH are created during the glycolysis process. In the Krebs cycle, pyruvate enters the inner matrix of mitochondria and undergoes oxidation.Oxidative phosphorylation- The process of oxidative phosphorylation is the transfer of electrons from NADH or \[FADH_2\] to \[{O_2}\] via a succession of electron carriers, resulting in the formation of ATP molecules. A cell's mitochondria are involved in this process.Citric acid cycle- This is also known as the Krebs cycle or the tricarboxylic acid cycle. Each phase of the citric acid cycle produces two ATP molecules and takes place within a cell's mitochondrial matrix. The Krebs cycle generates electrons that go across the mitochondrial matrix.Recently Updated PagesBasicity of sulphurous acid and sulphuric acid areMaster Class 11 Business Studies: Engaging Questions & Answers for SuccessMaster Class 11 Computer Science: Engaging Questions & Answers for SuccessMaster Class 11 Economics: Engaging Questions & Answers for SuccessMaster Class 11 Social Science: Engaging Questions & Answers for SuccessMaster Class 11 English: Engaging Questions & Answers for SuccessBasicity of sulphurous acid and sulphuric acid areMaster Class 11 Business Studies: Engaging Questions & Answers for SuccessMaster Class 11 Computer Science: Engaging Questions & Answers for SuccessMaster Class 11 Economics: Engaging Questions & Answers for SuccessMaster Class 11 Social Science: Engaging Questions & Answers for SuccessMaster Class 11 English: Engaging Questions & Answers for Success
