Summary. Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose.

How does anaerobic organisms obtain energy?
They lack mitochondria which contain the oxidative phosphorylation pathway, which in all other animals combines oxygen with glucose to produce metabolic energy, and thus they consume no oxygen. Instead these loricifera derive their energy from hydrogen using hydrogenosomes.
How much amount of energy is released during anaerobic respiration?
During anaerobic respiration, the oxidation of glucose is incomplete. The reaction therefore releases much less energy – around a nineteenth of the energy released during aerobic respiration. Only two ATP molecules of chemical energy are produced, in comparison with 38 molecules in aerobic respiration.
How is energy used in anaerobic respiration?
Answer: During anaerobic cellular respiration, glucose is broken down without oxygen. The chemical reaction transfers glucose energy to the cell. In fermentation, instead of carbon dioxide and water, lactic acid is produced which can lead to painful muscle cramps.
Why is more energy released in anaerobic respiration?
In anaerobic respiration, glucose breakdown is incomplete, so less energy is released. In aerobic respiration, complete breakdown of glucose takes place, therefore more energy is released. Aerobic respiration releases 38 ATPs, which is 19 times greater than 2 ATPs that are released during anaerobic respiration.
How do anaerobic organisms make ATP?
Some organisms and types of cells retain the older, anaerobic pathways for making ATP; these pathways comprise anaerobic respiration or fermentation. Obligate aerobes require oxygen to make ATP. ... Both alcoholic and lactic acid fermentation pathways change pyruvate in order to continue producing ATP by glycolysis.
How much ATP does anaerobic respiration produce?
Anaerobic cell respiration (glycolysis + fermentation) produces 2 ATP/glucose consumed. Aerobic cell respiration (glycolysis + the Krebs cycle + respiratory electron transport) produces 36 ATP/glucose consumed. Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration.
Why is the energy released during anaerobic respiration much less than the energy released during aerobic respiration?
Anaerobic respiration in muscles
Glucose is not completely broken down, so much less energy is released than during aerobic respiration. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.
Why energy released during anaerobic respiration is less as compared to Aerobicrespiration?
In anaerobic respiration, less energy is extracted. In this process only 02 ATP molecules are produced by each glucose molecule and the glucose molecules are partially broken down. The reaction yields less energy as compared to the aerobic respiration because the end product is alcohol and not carbon dioxide.
How much energy does respiration release?
In aerobic conditions, the process converts one molecule of glucose into two molecules of pyruvate (pyruvic acid), generating energy in the form of two net molecules of ATP.
How do the quantities of ATP formed during aerobic and anaerobic respiration compare?
Summary. Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose.
How do aerobic and anaerobic respiration differ in terms of energy output?
Aerobic: Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. ... Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen.
What statement best compares aerobic and anaerobic respiration?
Which statement best compares aerobic and anaerobic respiration? Less ATP is generated during anaerobic respiration than during aerobic respiration.
Which produces more energy aerobic or anaerobic?
With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.
How much energy is released in aerobic and anaerobic respiration?
Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose.
