Activity: What's the Difference! Complete the table on the differences of aerobic and anaerobic respiration according to the basis of comparison below: Basis for Aerobic respiration Anaerobic respiration comparison Anaerobic respiration is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives. Definition 1. The overall equation of aerobic respiration is: The overall equation of anaerobic respiration is: Overall equation C2H5OH + C6H1206 + 602 6CO2+ 6H2O + energy C6H1206 CO2 + energy Aerobic respiration takes place in the presence of oxygen 2. Presence of Oxygen The exchange of gases doesn't take place during anaerobic respiration. However, some gases like sulfur and nitrogen gases are released by some organisms. Exchange of gases 3. Aerobic respiration, after glycolysis, occurs in the mitochondria of eukaryotes and cytoplasm of prokaryotes. Location 4.
Electron Transport Chain
The electron transport chain, also known as the electron transport system, is a group of proteins that transfer electrons through a membrane within mitochondria to create a gradient of protons that drives adenosine triphosphate (ATP)synthesis. The cell uses ATP as an energy source for metabolic processes and cellular functions. ETC involves series of reactions that convert redox energy from NADH (nicotinamide adenine dinucleotide (NAD) + hydrogen (H)) and FADH2(flavin adenine dinucleotide (FAD)) oxidation into proton-motive force(PMF), which is then used to synthesize ATP through conformational changes in the ATP synthase complex, a process known as oxidative phosphorylation.
Metabolism
Picture a campfire. It keeps the body warm on a cold night and provides light. To ensure that the fire keeps burning, fuel needs to be added(pieces of wood in this case). When a small piece is added, the fire burns bright for a bit and then dies down unless more wood is added. But, if too many pieces are placed at a time, the fire escalates and burns for a longer time, without actually burning away all the pieces that have been added. Many of them, especially the larger chunks or damp pieces, remain unburnt.
Cellular Respiration
Cellular respiration is the cellular process involved in the generation of adenosine triphosphate (ATP) molecules from the organic nutritional source obtained from the diet. It is a universal process observed in all types of life forms. The glucose (chemical formula C6H12O6) molecules are the preferred raw material for cell respiration as it possesses a simple structure and is highly efficient in nature.
