Aerobic respiration produces more oxygen than anaerobic respiration. Aerobic metabolism takes more time than anaerobic respiration. The rate of ATP production in the mitochondria is directly proportional to the amount of oxygen consumed by the cell. This is called the respiratory quotient (RQ). The higher the RQ, the more energy is available for ATP synthesis.
For example, if a cell has a high oxygen consumption rate, then it will have a higher ATP turnover rate than a low-oxygen-consumption cell, because it has more oxygen available to use for energy production. However, this is not always the case. A cell that consumes a lot of carbon dioxide (CO2) may not have the energy to synthesize ATP.
In this case, it may be more efficient to produce ATP from glucose (glucose-6-phosphate) or from fatty acids (palmitic acid) instead of from CO2.

Does anaerobic produce more ATP?
There is a summary. Aerobic respiration is more efficient than anaerobic respiration. The aerobic processes can produce up to 38 ATP. The anaerobic processes only yield 2 sugars. This means that the amount of energy that can be stored in the body is limited by the rate at which it is being used.
The rate of ATP production is directly related to the intensity of the exercise. The more intense an exercise is, the more ATP is produced and the less energy is required to produce it.
For example, if you are running at a moderate pace for 30 minutes, then you will produce an average of 2.5 ATP for every glucose that you consume.
If you were to run for an hour at the same pace, however, you would produce only 1.2 ATP, which is less than half of what you need to store in order to maintain your current level of fitness.
Why aerobic respiration produces more ATP than anaerobic?
The complete oxidation of glucose to CO2 and water makes aerobic respiration more efficient. O2 is reduced to water when it acts as the terminal electron acceptor. The majority of the ATPs are produced by the mitochondria. ATP is converted to adenosine triphosphate, which can be used as an energy source for the cell.
ATP is also used to produce adenylyl cyclase, the enzyme that converts ADP to ATP. This enzyme is found in all cells, but it is most abundant in skeletal muscle, where it plays an important role in energy production. It also is present in many other tissues, including the brain, heart, liver, kidney, pancreas, spleen, bone marrow, and other organs.
Why does anaerobic produce less ATP than aerobic?
The cytoplasm of cells is where anaerobic respiration occurs. Aerobic respiration releases more ATP than does Glucose, because it is not completely broken down. The Krebs cycle converts the lactic acid into pyruvate when it is oxidised.
In the absence of oxygen, there is no energy source for the mitochondria to use to break down the glucose. This is the reason why the body can’t use glucose as a fuel source, and why it has to rely on fatty acids and ketone bodies to provide energy.
Why does anaerobic respiration produce less energy?
Anaerobic respiration produces less energy because of the incomplete breakdown of the respiratory substrate. Some of the products of anaerobic respiration can be released further to release energy, which shows that it does not liberate as much energy as aerobic metabolism. Aerobic metabolism produces more energy per unit of oxygen consumed than aerobic. This is due to the fact that more oxygen is consumed in an aerobic process than in a non-accelerated process.
In addition, the oxygen used in aerobic processes is used to produce energy, which is not available to be used by the body as a source of energy. Therefore, it is more efficient to use oxygen as an energy source than to convert it to carbon dioxide (CO 2 ) or water (H 2 O) as is the case in the aerobic system.
It is important to note that the amount of CO 2 that is produced by aerobic and aero-oxidative metabolism is very small compared to that produced from the oxidation of carbohydrates, fats, proteins, and nucleic acids (DNA and RNA). This means that there is no significant difference in energy production between the two systems. However, there are differences in how these energy sources are used.
Why is less energy produced in anaerobic respiration compared to aerobic respiration?
The end product of the aerobic process is carbon dioxide and there is no oxygen as the final electron acceptor, so the energy production in the form of ATP is less than in the aerobic process. Less energy production is caused by all these factors.
It is also important to note that the amount of energy that is produced by aerobic metabolism is only a small fraction of the total energy available to the body. In fact, it is estimated that only 10-15% of all the energy is available for use. The rest is stored as glycogen, fat, and water.
This is why it can be so difficult to lose weight and maintain a healthy body weight.
Why is anaerobic respiration faster than aerobic?
Less energy is produced for every molecule of glucose broken down, which means less energy is required to produce the same amount of energy.
Aerobic glycogenolysis, on the other hand, requires a lot more energy to break down the glucose, which is why it takes longer for the body to use it.
This is also why you need to eat more carbohydrates to fuel your workouts, as your body can only use so much carbohydrate at a time.
Why less ATP are produced in anaerobic glycolysis?
The reduced cofactor, which is formed by GAPDH, is reconverted to its original form during the formation of lactate. The primary source of energy for the mitochondria is the turnover of glycolytically derived ATP.
In contrast, in aerobic respiration, ATP is produced from the oxidation of pyruvate in the Krebs cycle, which is a non-enzymatic process that requires the presence of oxygen.
In this process, oxygen is used to oxidize the carbon dioxide (CO 2 ) to carbonic acid (H 2 CO 3 ), which in turn is oxidized to acetyl-CoA (C 6 H 12 O 6 ). This process is called oxidative phosphorylation, and it is thought to be responsible for most of the energy production in cells.
However, there are some exceptions to this general rule.
