How much more energy does aerobic respiration produce compared to anaerobic?

How much more energy does aerobic respiration produce compared to anaerobic?

Aerobic respiration vs anaerobic respiration Aerobic respiration releases 19 times more energy than anaerobic respiration from the same amount of glucose.

Does aerobic respiration produce the most energy?

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.

Which produces more energy anaerobic or aerobic?

Aerobic respiration produces more ATP than anaerobic respiration due to the complete oxidation of glucose to CO2 and water.

How much energy is produced in an aerobic respiration in ATP?

2 ATP molecules
Hence, the amount of oxygen required to oxidize lactic acid to carbon dioxide and water is not present. Aerobic respiration produces 38 ATP whereas anaerobic respiration produces only 2 ATP molecules.

Why does aerobic respiration give more energy?

Advantages of Aerobic Respiration 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.

Why is aerobic respiration more efficient?

Aerobic respiration is much more efficient, and produces ATP much more quickly, than anaerobic respiration. This is because oxygen is an excellent electron acceptor for the chemical reactions involved in generating ATP.

Which respiration is much efficient?

Aerobic respiration
Aerobic respiration is the most efficient form of respiration. Theoretically, there can be a net gain of 38 ATP molecules by the complete oxidation of one glucose molecule in aerobic respiration.

How much energy is produced during anaerobic respiration?

2 ATP
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.

How much energy is produced in aerobic respiration in kJ?

About 3000 kJ mol-1
Aerobic respiration About 3000 kJ mol-1 of energy is released. Burning glucose in air would release this amount of energy in one go.

Why does anaerobic respiration produce less energy?

Anaerobic respiration happens in muscles during hard exercise. Glucose is not completely broken down, so 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 is aerobic respiration less efficient?

Expert-verified answer Much less energy is released during anaerobic respiration than during aerobic respiration. This is because the breakdown of glucose is incomplete. Anaerobic respiration produces an oxygen debt. This is the amount of oxygen needed to oxidise lactic acid to carbon dioxide and water.

Why is aerobic respiration more efficient than glycolysis?

1 Answer. Glycolysis gives only 2 ATP molecules as a net amount of energy by the end, while the full aerobic respiration gives 36-38 (based on different references) net molecule in net by the end.

How much energy is released in aerobic respiration in kJ?

Aerobic respiration About 3000 kJ mol-1 of energy is released. Burning glucose in air would release this amount of energy in one go. However, it is not as simple as this in aerobic respiration.

How much energy is produced in anaerobic respiration in kJ?

Anaerobic respiration Each time this biochemical reaction takes place it the ΔG for the reaction = -118 kJoules.

Why does aerobic respiration produce less energy than aerobic respiration?

The energy production in the form of ATP is much less than in the aerobic process as the end product is not carbon dioxide and there is no oxygen as the final electron acceptor.

How are 38 ATP produced?

Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
