Aerobic respiration has four stages: Glycolysis, formation of acetyl coenzyme A, the citric acid cycle, and the electron transport chain.
What is the process of respiration?
Aerobic respiration is a biological process that takes energy from glucose and other organic compounds to create a molecule called Adenosine TriPhosphate (ATP). ATP is then used as energy by nearly every cell in the body -- the largest user being the muscular system.
Where does glycolysis take place?
This step takes place within the cytosol of the cell, and is actually anaerobic, meaning it does not need oxygen. During glycolysis, which means breakdown of glucose, glucose is separated into two ATP and two NADH molecules, which are used later in the process of aerobic respiration. Advertisement.
How many turns of the citric acid cycle are needed to break down the original acetyl coenzy?
Two turns of the citric acid cycle are required to break down the original acetyl coenzyme A from the single glucose molecule. These two cycles create an additional two ATP molecules, as well as six NADH and two FADH molecules, all which are used later. Advertisement.
What is aerobic cellular respiration?
Aerobic cellular respiration refers to the process by which living organisms convert nutrients into energy for the body to use via the oxidization of nutrients. During aerobic respiration, catabolic reactions convert larger complex organic molecules into ATP, the chemical ...
Why is aerobic respiration important?
Aerobic respiration is fundamental as it allows for the production of ATP, the molecule that drives every physiological process in every known living organism. The high energy yield of aerobic respiration allows for complex multicellular life and is occurring all the time in every cell of the body.

Aerobic cellular respiration is the most basic metabolic pathway found in eukaryotic organisms. Aerobic respiration is fundamental as it allows for ...
How many ATP molecules are produced by oxidation of NADH?
In actual cells though, energy is always lost due to heat dissipation and proton leakage, making the average total yield around 29-30 molecules of ATP per molecule of glucose. Oxidative phosphorylation marks the terminal point of the cellular respiration and the main sequence that accounts for the high ATP yield of aerobic cellular respiration.
How is pyruvate formed?
Once pyruvate is formed from glycolysis, the body still needs to process the pyruvate to access the chemical energy stored in its bonds. In the second step of cellular respiration, pyruvate molecules produced by glucose are transported to the cell’s mitochondria and are oxidized to produce acetyl-CoA, an enzyme the provides the acetyl base for ...
What is the first step in the chain of catabolic reactions?
Glycolysis is the first step in the chain of catabolic reactions the comprise the process of cellular respiration. During glycolysis, monosaccharides (simple sugars) such as glucose, sucrose, or fructose are converted into pyruvic acid. Incidentally, the word “glycolysis” literally means “splitting sugar.” The whole sequence of glycolysis is comprised out of 10 individual reactions, each of which is catalyzed by a different enzyme. Glycolysis takes place in the cytoplasm, the jelly-like substance that fills the inside of cells. For every 1 molecule of glucose, glycolysis produces 2 molecules of pyruvate, 2 molecules of NADH, and 2 molecules of ATP.

The process of aerobic respiration involves 4 main steps: glycolysis, production of acetyl-CoA, the citric acid cycle, and oxidative phosphorylation. Each step involves the conversion of one or more chemical substances to utilize ...
Where does respiration occur?
The first stages of respiration occur in the cytoplasm of plant and animal cells, but most of the stages of respiration that release energy happen in the mitochondria. Microorganisms do not have mitochondria - they carry out respiration only in the cytoplasm.
Which organisms can respire anaerobically?
Some plants, microorganisms and fungi such as yeast can respire anaerobically - it's preferable to release less energy and make less ATP but remain alive.
Can anaerobic respiration occur without oxygen?
Anaerobic respiration. Most organisms cannot respire without oxygen but some organisms and tissues can continue to respire if the oxygen runs out. In conditions of low or no oxygen the process of anaerobic respiration occurs. The 'an' in 'anaerobic' means without.
How do cells get energy?
All cells need energy to survive. They obtain this energy by carrying a series of chemical reactions that are collectively known as respiration.
Is carbon dioxide a waste product of aerobic respiration?
Aerobic respiration breaks down glucose and combines the broken down products with oxygen, making water and carbon dioxide. The carbon dioxide is a waste product of aerobic respiration because cells do not need it.
Is glucose released during anaerobic respiration?
During anaerobic respiration, the oxidation of glucose is incomplete - not all of the energy can be released from the glucose molecule as it is only partially broken down. The reaction therefore releases much less energy than aerobic respiration - around only a nineteenth of the energy released during aerobic respiration. This means that fewer molecules of ATP can be made.
What is aerobic respiration?
Aerobic Respiration is the process by which the energy from glucose is released in the presence of oxygen. It takes place only if oxygen is available. ADVERTISEMENTS: For instance, if glucose were oxidized, the result would be energy, carbon dioxide and water. Take a look at the chemical formula given below.
What is the energy released during aerobic respiration?
In this stage of aerobic respiration, remaining energy from the glucose will be released by the electron transport chain. The network of electrons carrying proteins to the inner membrane of the cell is known as electron transport chain. Eventually, in this stage the electrons along with the protons will be added to oxygen.
What is the next stage of the cellular respiratory cycle?
This is the next stage of aerobic cellular respiratory. In Krebs cycle, private molecules are processed to release the energy that is stored between their molecular bonds. The energy is released in the form of ATP. This cycle is also called as the citric acid cycle.
How many stages of aerobic respiration are there?
There are three stages of aerobic respiration as given below:
What is the process of adding protons and electrons to oxygen?
Actually, when the protons are moved across the cell membrane, ATP is produced. This process is called as chemiosis. Cellular Respiration. Various Types of Cells (Bacterial Cells and Fungi Cell) | Biology.
