ATP synthase. Answers: 1 on a question: 20 pts! Aerobic vs Anaerobic Similarities This forces the cell to undergo the much less efficient fermentation. Anaerobic respiration is a critical component of the global nitrogen, iron, sulfur, and carbon cycles through the reduction of the oxyanions of nitrogen, sulfur, and carbon to more-reduced compounds. We have moved all content for this concept to for better organization. Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration. ATP synthase. Glycolysis produces energy by partially breaking down glucose into 2 molecules of pyruvate. Aerobic respiration requires oxygen, whereas anaerobic respiration takes place in the absence of oxygen. Your cells require a lot of energy and are dependent on the high efficiency of aerobic respiration. What is the main advantage of aerobic respiration? Unlike aerobic respiration, anaerobic respiration does not need oxygen. Anaerobic reparation requires less energy because it does not require oxygen. Of course, what this means is that the breakdown of glucose in the presence of oxygen generates more usable energy for the cell than without. However, instead of ending with glycolysis, as fermentation does, anaerobic respiration creates pyruvate and then continues on the same path as aerobic respiration. Aerobic respiration. C. aerobic respiration needs more oxygen. Actually, aerobic (cellular) respiration is more efficient than anaerobic, not more effective.

Overall, aerobic respiration converts about 40% of the available energy of glucose into ATP. Respiration takes put in place every living cellular, all of the time and all cells need to respire as a way to produce the energy them to require. • First, aerobic respiration uses oxygen well. Why is that aerobic respiration more efficient than anaerobic respiration? Aerobic respiration is cellular respiration that uses oxygen as a terminal electron acceptor to generate energy from glucose breakdown. This is because the breakdown of glucose is incomplete. Aerobic respiration is 19 times more effective at releasing energy than anaerobic respiration because aerobic processes extract most of the glucose molecules' energy in the form of ATP, while anaerobic processes leave most of the ATP-generating sources in the waste products. Overall, aerobic respiration converts … However, it creates less ATP molecules because of this. © copyright 2003-2021 Study.com. The process releases less energy than aerobic respiration.

Overall, aerobic respiration converts about 40% of the available energy of glucose into ATP. Cellular respiration is a process that takes place inside the cells where energy is released by the breakdown of glucose molecules. Up Next. 14.6/686 x 100= 2.12%. Without oxygen, organisms can split glucose into just two molecules of pyruvate. Aerobic respiration is much more efficient, and produces ATP much more quickly, than anaerobic respiration. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Select the correct answer. Hence aerobic respiration is more efficient. The first step is still glycolysis, and it still creates 2 ATP from one carbohydrate molecule. Aerobic respiration is more efficient than anaerobic respiration because aerobic respiration produces 38 ATPs for one glucose molecule. D Less lactic acid is formed during anaerobic respiration than during aerobic respiration. Unlike aerobic respiration, anaerobic respiration does not need oxygen. Practice: Cellular respiration. The process can be conveniently divided into two categories based on the usage of oxygen, namely aerobic and anaerobic respiration. Aerobic respiration is the respiratory pathway of choice for oxygen-dependent organisms because of its greater efficient. The respiration can be aerobic, which uses glucose and oxygen, or anaerobic which uses only glucose. Both aerobic and anaerobic respiration use electron-transport chain-reaction pathways in energy production. This is because the breakdown of glucose is incomplete. 2 ATP x 30.6 kJ = 61.2 kJ is conserved in anaerobic respiration of each glucose molecule. Sort by: Top Voted.
