The human body has 3 main methods for using energy to sustain itself and fuel exercise. 2. Aerobic respiration refers to complete breakdown of metabolic fuels in presence of oxygen. includes all the reactions by which the body obtains and expends the energy from food. In anaerobic respiration, the electron acceptor can be sulfate ion (SO 4 â ) or nitrate ion (NO 3 â ) or a variety of other molecules. Is respiration and breathing same? Pyruvate is the output of the anaerobic metabolism of glucose known as glycolysis. how does it occur ? Examples include sprints, interval training and heavy weightlifting. brainly.in/question/5380893. 1. the sum total of all the chemical reactions that go on in living cells. The processes of _____ would yield the highest number of ATP. 1. The difference between aerobic and anaerobic respiration. metabolism. Write the chemical equation of anaerobic respiration in muscle cell - 17543535 Unlike aerobic exercise, which uses oxygen for a sustained workout, anaerobic training lasts only seconds to at most two minutes. Energy metabolism. Aerobic respiration Anaerobic respiration. - 6483676 Answer: Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain. â Anaerobes require an absence of oxygen and presence of different nutrients from the aerobic counterparts a 3-carbon compound produced from pyruvate during anaerobic metabolism. Aerobic metabolism is 19 times more efficient than anaerobic metabolism (which yields 2 mol ATP per 1 mol glucose). These physiological pathways are called energy systems, and the most important of these for endurance athletes is the aerobic energy system.Letâs take a closer look at how your body utilizes the aerobic system to power you on your bike, and how you can train this system to be more efficient and effective. Anaerobic respiration is the process of partial breakdown of fuel (glucose) in absence of oxygen. A) glycolysis B) fermentation C) oxidative phosphorylation (electron transport chain) D) the Krebs Cycle What is respiration ? brainly.in/question/3477700 acetyl CoA. Both aerobic and anaerobic respiration yield a net gain of ATP molecules to be used as energy for living things. Learn more about respiration. Brainly User Brainly User â The presence of oxygen , nutrients and space to discard their metabolic products are the conditions for cellular respiration in aerobic organisms . Anaerobic exercise is a very short, very intense exercise that doesn't use oxygen for fuel. They share the initial pathway of glycolysis but aerobic metabolism continues with the Krebs cycle and oxidative phosphorylation. Pathways for aerobic and anaerobic respiration. Anaerobic respiration is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives. Aerobic Respiration :-The respiration which takes place in the presence of oxygen is known as the aerobic respiration..
