List some similarities and differences between aerobic and anaerobic respiration
Answers
Answer:
Aerobic Respiration
Glucose and oxygen interact to release energy with carbon dioxide and water as byproducts. It is so efficient that 38 molecules of ATP may be produced per glucose molecule. The chemical stages of aerobic respiration occur in 1. the cytosol: glycolysis, and 2. the mitochondria: the Krebs Cycle -- in which pyruvate serves as one substrate in the pathway -- and electron transport. Aerobic respiration provides energy for prolonged, less intense workouts when the body is able to take in and deliver enough oxygen to cells to support this more efficient means of generating ATP.
Anaerobic Respiration
In the absence of oxygen, glycolysis takes place during anaerobic respiration as it does during aerobic respiration. The next stages, however, differ significantly, and no more ATP beyond the two molecules produced during glycolysis is generated. In humans and other animals, pyruvate is then converted in the cytosol into lactic acid and water. A byproduct of anaerobic respiration, lactic acid, contributes to muscle fatigue and discomfort. When you pant or “catch your breath” after exercising, your body is trying to take in enough oxygen to reestablish a chemical state capable of cleaning up unwanted byproducts such as lactic acid that build up when oxygen is in short supply.
Explanation:
similarities
Both aerobic and anaerobic respirations are types of cellular respiration. It is clear both use glycolysis to produce ATP. Both generate energy by breaking down glucose, produce byproducts and depend on chemical reactions that are localized in the cytosol. Both use pyruvate as a substrate, and of course, both processes depend on enzymes to catalyze their respective chemical reactions.
