Anaerobic respiration. Aerobic Respiration: This process takes place in the presence of oxygen to produce energy. It can be observed in all types of eukaryotic cells. Anaerobic Respiration: This process takes place in the absence of oxygen and can generally be observed in human muscles cells, prokaryotes and methanogens.
In general terms, respiration is a chemical process whereas breathing is a chemical process. Both are inter-related but their mechanisms vary. Below we will have a look at the different characteristics between breathing and respiration. Comparison Basis. Breathing is the process of inhaling oxygen from the environment and exhaling carbon dioxide back to it with the help of the lungs. It is a process where glucose and oxygen are broken down to produce energy which is used for cellular activities.
It is a biophysical voluntary process which happens in two stages i inhalation and ii exhalation. It is a biochemical involuntary process which takes place through i glycolysis ii Krebs cycle. Where does it take place? It takes place in the lungs or gills. It takes place in cells. Energy production. No energy is produced in this process. Energy is produced in the form of ATP. Cellular activity.
Breathing is an extracellular process. Respiration is an intracellular process. Cellular respiration, also termed as internal respiration, occurs in living cells. The oxygenated blood is carried to all living cells in the body of an organism through blood circulatory. Cellular respiration involves breakdown of glucose into carbon dioxide and water in presence of oxygen, releasing energy. Oxygen carried by blood is used in cellular respiration and carbon dioxide released combines with hemoglobin in RBCs.
Deoxygenated or impure blood is carried by veins to the lungs to be converted into oxygenated blood. The energy released during cellular respiration is stored in form of ATP molecules, which are store houses of energy.
ATP molecule is converted into ADP molecule, whenever energy is needed for any metabolic reaction or activity. The energy stored in it is released to be used in metabolic reaction. How do cellular respiration and breathing differ? Krishan T. Overview and Key Difference 2. What is Respiration 3. What is Cellular Respiration 4. Similarities Between Respiration and Cellular Respiration 5. In physiology, respiration is described as the movement of oxygen molecules from outside environment to the inner cells and the movement of carbon dioxide from inner cells to the outside environment in the opposite direction.
It is also known as breathing. The movement of oxygen into the cells is defined as inhalation. And the movement of carbon dioxide to the outside environment is defined as exhalation.
Inhalation is an active process. The diaphragm is contracted, and internal height of the thoracic cavity is increased. The internal pressure decreases and atmospheric oxygen moves inside the respiratory tract.
The exhalation is a passive process. During the exhalation, the diaphragm relaxes and decreases the volume of the thoracic cavity. Then the internal pressure increases. Hence, carbon dioxide moves out of the respiratory tract to the outside environment. Inhalation brings oxygen to the lungs, and the gas exchange takes place between air in the alveoli and blood in the pulmonary capillaries. The carbon dioxide in return moves from blood to alveoli air and out of the respiratory tract.
In biochemical means, the respiration is defined as cellular respiration. In the cellular respiration, the glucose is broken down into carbon dioxide and water in the presence of oxygen. The resulted energy is stored in ATP where it is used in metabolism. Energy is needed to keep the life processes constantly. It is extremely important in life processes such as growth and development, movement, repair and the control of body temperature in mammals etc.
The cellular respiration is an energy generating biochemical reaction which takes place in all living cells including plant and animal cells. The energy that is released from glucose can be used in other living cells for biochemical reactions like catabolic and anabolic pathways.
