Oxygen is NOT needed to produce ATP. This is only true for Oxidative Phosphorylation. Substrate Level Phosphorylation does not require ATP at all.
While ATP can be produced without oxygen via a process called anaerobic respiration, aerobic respiration is a much more efficient means of ATP production. Aerobic respiration is the release of energy from glucose or another organic substrates in the presence of Oxygen. Strictly speaking aerobic means in air, but it is the Oxygen in the air which is necessary for aerobic respiration. Anaerobic respiration is in the absence of air. Aerobic respiration takes place in almost all living things. It is easy to get rid of the Carbon Dioxide and excess water; this is excretion (the removal of the toxic waste products of metabolism), and maximum energy is released from the glucose. Some organisms can respire in the absence of air: this is anaerobic respiration. This does not release so much energy and it produces much more toxic waste products. However, if Oxygen is not available, anaerobic respiration is better than nothing. When this happens in our muscles we produce lactic acid which gives you cramp.

∙ 15y agoNo. Some organisms live entirely anaerobic lives, yet still produce ATP.
In the cellular respiration of glucose, the first stage, which is called glycolysis and takes place in the cytoplasm, results in the formation of two molecules of pyruvate for each glucose molecule respired. During glycolysis, after an initial investment of two ATP molecules, the cell obtains enough energy to synthesize four molecules of ATP, a net gain of two. The entire process of glycolysis is anaerobic.
The pyruvate may then go into mitochondria to be oxidized aerobically, or remain in the cytoplasm to be converted anaerobically into ethanol (in yeast or plants) or lactate (in humans and other animals). If the cell uses one of these latter anaerobic pathways, there is no further production of ATP.

∙ 13y agoNo, because some cells live in anaerobic conditions (no oxygen) which means that they produce energy through Glycolysis (glucose molecule is broken down into two pyruvate). So oxygen is not necessary, but that process results in a small amount of ATP and for optimal amounts of ATP oxygen is necessary for oxidative phosphorylation.

∙ 13y agoNot necessarily. People can make more ATP when oxygen is present, but it can also make about 2 ATP without oxygen. In other words, ATP can be made without oxygen in organisms by a process called fermentation. So my answer is no. Look up fermentation process if you don't know what it is.^^

Why do animals need a continuous supply of oxygen?
Animals need a continuous supply of oxygen because it obtains energy from their food. To acquire such energy from food, cells in animals require a steady supply of ATP in order to function. To produce this ATP, cellular respiration requires oxygen. Without ATP, cells and the organism will die so therefore, animals need a continuous supply of oxygen to survive.
The complete breakdown of glucose in the presence of oxygen yields how many molecules of ATP?
36 molecules by oxydative phosphorylation.
What can living things do?
1.They can produce food. 2.They can grow. 3.They can produce oxygen. This is only for plants who produce food Animals can find their own food they can not produce it. they grow and develop and they dont produce oxygen
The energy needed for active transport is usually supplied by what?
The energy needed for active transport is usually supplied by Mitochondria and ATP.
Which gas do plants produce?
Oxygen, we pretty much breathe and exhale the complete opposite gases that plants do. Most green plants take in carbon dioxide and produce oxygen.
What is the main purpose of fermentation reactions?
Fermentation is a pathway used under anaerobic conditions. It is needed to produce ATP when there is no oxygen present.
Cells produce ATP most efficiently in the presence of what molecule?
Oxygen. Cells can produce much more ATP from glucose in the presence of Oxygen (aerobic respiration) than without oxygen (anaerobic respiration) in a process called oxidative phosphorylation that occurs in the mitochondria of cells. In the presence of oxygen one glucose can be broken down to produce 36 ATP Without oxygen, only 4 ATP can be made
Why ATP produce more ATP than the other?
More ATP is produced during cellular respiration using oxygen than without oxygen.
What does oxygen allow humans o do?
produce atp from food
What substances does the body need when exercising?
The body mostly needs fats which are used to produce energy. The body also needs water which is used for cooling and other important functions.
What does oxygen do as a component of blood?
Oxygen is used to produce ATP in the mitochondria, which powers our cells to do its functions.
Why do animal cells need oxygen most directly?
Produce ATP
What is needed to produce energy?
many things. one, energy source. For humans, that's food and oxygen. Oxygen is used in aerobic respiration, which produces about 32 ATP (which is energy that our body can use). Food contains nutrients and sugars that help produce energy. ATP can be used to restart the cycle, and break down food to yield more ATP/energy. As for something like plants, they use photosynthesis. This uses the Sun's light as energy to "kick-start" the energy process. they use Anerobic (as suppose to human's aerobic) respiration. this yield about 8 ATP (which as you can see, is less than the 32 ATP aerobic respiration yeilds). They then use that ATP to carry out all of it's functions, since ATP is energy.So to sum it all up,Oxygen (only in aerobic respiration), ATP, light (sun's light), and Carbon are needed to produce energy.
How do a muscle produce ATP?
creatine phosphate, anerobic cellular respiration, and areobic cellular respiration all produce ATP.
The complete process which is needed to produce ATP is called the?
Krebs cycle
How can a skeletal muscle produce additional ATP when there is not enough oxygen?
Anaerobic fermentation enables a cell to produce ATP in the absence of oxygen but the ATP yield is very limited and the process produces a toxic end product, lactic acid, which is a major factor in muscle fatigue.
What process makes oxygen?
I am not sure that there is such a process that produces ATP and oxygen, however, there are 2 processes that produce ATP, while one reqires oxygen, and the other does not. The process that produces ATP and does require oxygen is called aerobic respiration. While the process that produces ATP but does not need oxygen is called anaerobic respiration.
