What are the steps in aerobic respiration?
The main steps of aerobic respiration are as follows:
- Glycolysis- Cytoplasm.
- Krebs cycle- Matrix of mitochondria.
- Electron transport system- Inner mitochondrial membrane.
- Oxidative phosphorylation- Oxysome in the inner mitochondrial membrane. Similar Questions.
What is the Order of aerobic respiration?
The four stages of aerobic respiration are glycolysis, acetyl-CoA, Krebs cycle and the electron transport chain. Aerobic respiration is the process by which the body produces ATP, an important substance that is needed for the survival of cells. During the first phase, glycolysis, glucose is broken down in the cytoplasm of the cells.
What are the phases of aerobic respiration?

- Citric acid cycle.
- Electron transport.
What is the main advantage of aerobic respiration?
… ATP is available from the following sources:
- Within the muscle fiber. …
- Creatine phosphate. …
- Glucose stored within the cell. …
- Glucose and fatty acids obtained from the bloodstream.
Where is actually o2 is utilized during aerobic respiration?
The mitochondria would be unable to generate new ATP in this way, and the cell would ultimately die from lack of energy. This is the reason we must breathe to draw in new oxygen. This is the only place where oxygen is required during the processes of aerobic respiration.
How is oxygen used in aerobic respiration?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP.
What is aerobic respiration and anaerobic respiration?
Answer: Aerobic respiration: It is a process when glucose is broken down to carbon dioxide in the presence of oxygen to produce energy in the form...
2. How does aerobic respiration differ from anaerobic respiration?
Answer:Aerobic respiration takes place in the presence of free oxygen and anaerobic respiration takes place in the absence of oxygen.
3. How many ATP are produced in aerobic respiration?
Answer: 38 ATP molecules are produced during aerobic respiration.
4. Name the first product formed in the Krebs cycle.
Answer: The first product formed in the Krebs cycle is citric acid, hence it is also called the citric acid cycle.
5. What is the role of oxygen in aerobic respiration?
Answer: Oxygen is responsible for accepting electrons in the electron transport chain.
6. Name the pathway that is common between aerobic and anaerobic respiration.
Answer: Glycolysis or EMP pathway is the common pathway between aerobic respiration and anaerobic respiration.
7. Which step of aerobic respiration produces maximum ATP?
Answer: Oxidative phosphorylation produces maximum ATP, i.e. 34 ATP molecules are formed in this step.
Why do we need aerobic respiration?
Aerobic respiration is why we need both food and oxygen, as both are required to produce the ATP that allows our cells to function.
Which is more efficient, aerobic or anaerobic respiration?
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. An overview of the stages of aerobic respiration.
How does NADH work in cellular respiration?
This is important, as later in the process of cellular respiration, NADH will power the formation of much more ATP through the mitochondria ’s electron transport chain. In the next stage, pyruvate is processed to turn it into fuel for the citric acid cycle, using the process of oxidative decarboxylation.
How are aerobic and anaerobic respiration similar?
Similarities. Both aerobic and anaerobic respiration are methods of generating energy. They also both start in the same way, with the process of glycolysis. “Glycolysis” literally means “sugar splitting,” and involves breaking a sugar molecule down into two smaller molecules. In the process of glycolysis, two ATP molecules are consumed ...
What is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical?
Aerobic respiration is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy. In contrast, anaerobic respiration does not use oxygen.
What is the link reaction between glycolysis and the citric acid cycle?
Oxidative decarboxylation, sometimes referred to as the link reaction or the transition reaction, is the link between glycolysis and the citric acid cycle. Pyruvate is transfered into the mitochondrial matrix via a protein known as pyruvate translocase.
Why is acetyl-CoA important?
This transition reaction is important because acetyl-CoA is an ideal fuel for the citric acid cycle, which can in turn power the process of oxidative phosphorylation in the mitochondria , which produces huge amounts of ATP. More NADH is also created in this reaction.
What is Aerobic Respiration?
Aerobic respiration is a process in which the cells utilize oxygen for the degradation of primary metabolites and release energy. It takes place in the cytoplasm and mitochondria of the cell and produces ATP ( Adenosine Triphosphate ).
Why is aerobic respiration important?
Aerobic respiration plays a significant role in releasing a lot of energy which helps in the survival of life. These are the following importance of aerobic respiration: It releases a large amount of energy in comparison to anaerobic respiration. It carries out a complete breakdown of glucose into carbon dioxide.
What are the two types of cellular respiration?
The cellular respiration is of two types, i.e. aerobic respiration and anaerobic respiration . Aerobic respiration: It is a process when glucose is broken down to carbon dioxide in the presence of oxygen to produce energy in the form of ATP. Anaerobic respiration: It is a process when glucose is broken down in the absence of oxygen.
What is the process of breaking down glucose to produce energy in the form of ATP?
Cellular respiration is the process where a cell breaks down glucose to produce energy in the form of ATP. Cellular respiration can take place in the presence or absence of molecular oxygen.
