The Four Stages Of Cellular Respiration
Cellular Respiration
Cellular respiration is basically what cells do to break down sugars into a form that the cell can utilize as energy. Cellular respiration takes in food and uses it to create ATP. ATP is a chemical which the cell uses for energy. The are two forms of cellular respiration, aerobic and anaerobic respiration, in which will be explained. Regular cellular respiration is aerobic, meaning that it requires oxygen, but some simple organisms can only do anaerobic cellular respiration, which means that it does not require energy. The simplified formula/word equation for aerobic respiration is: Glucose (sugar) + Oxygen → Carbon dioxide + Water + Energy (as ATP). Aerobic cellular respiration has four stages. Each is important and could …show more content…
The primary objective of the Link Reaction is to create Acetyl CoA so that it may be used in the Krebs Cycle. The link reaction marks the beginning of the aerobic reactions. Aerobic is an adjective that means 'requiring oxygen' and in aerobic respiration, when a cell needs to release energy, the cytoplasm and mitochondria organelles begin chemical exchanges that results in the breakdown of glucose. Once the breakdown is complete, this sugar is carried through the bloodstream and stored in the body as a fast source of energy. In plants, the energy-releasing process of photosynthesis uses CO2 and releases oxygen as its by product. Another part if the link stage is Anaerobic …show more content…
The Krebs cycle provides the hydrogen and electrons needed for the electron transport chain (which is the final stage of cellular respiration) and it takes place inside mitochondria better known as the powerhouse of the cell. It is also where ATP is produced and utilized. The Krebs cycle begins with production of acetyl co-A, which is created by the combination of pyruvate with the enzyme coenzyme A. Acetyl co-A then combines with oxaloacetic acid, creating the six-carbon molecule of citric acid. Once this happens a series of enzymatic catalysts propel as many as ten reactions of the Krebs cycle. The catalysts transform various molecules, such as NAD (nicotinamide adenine). The molecule NAD receives high energy electrons transmitted by multiple enzymatic steps. NAD forms NADH after binding to the electrons. During the Krebs cycle, two molecules of ATP are created which will fuel the cellular process of any living
