Yes.
In a cell the only pathway that oxidizes pyruvate is the series of reactions in the mitochondria that lead eventually to complete oxidation to carbon dioxide and water. This process requires oxygen as a final acceptor of the hydrogen atoms removed during this oxidation.
The complete pathway involves the link reaction and the reactions of the Krebs (citric acid) cycle.
What else can I help you with?
In cellular respiration why do you need oxygen and exhale carbon dioxide?
oxygen picks up electrons from the oxidation of glucose at the end of the electron transport chain. carbon dioxide results from the oxidation of glucose. it is released in the groooming of pyruvate and citric acid cycle [also known as the Kreb's cycle].
Why can glycolysis supply energy to cells when oxygen is not avalable?
Glycolysis can occur without oxygen. Although glycolysis does not require oxygen, it does require NAD+. Cells without oxygen available need to regenerate NAD+ from NADH so that in the absence of oxygen, at least some ATP can be made by glycolysis.
If a cell has no oxygen what stages of aerobic cellular respiration can still run?
If there is no oxygen available, only glycolysis can still run in anaerobic conditions. The Krebs cycle and electron transport chain, both of which require oxygen, cannot proceed. Glycolysis produces ATP by breaking down glucose into pyruvate without the need for oxygen.
What three components need to exist for bioluminescence to occur?
The three components needed for bioluminescence to occur are a light-emitting molecule (luciferin), an enzyme (luciferase), and oxygen. Luciferin reacts with oxygen in the presence of luciferase to produce light.
What happens during anaerobic respiration?
During anaerobic respiration, cells produce energy without the presence of oxygen. The process begins with glycolysis, where glucose is broken down into pyruvate. In the absence of oxygen, pyruvate is converted into either lactic acid in animals or alcohol and carbon dioxide in yeast and some bacteria, generating a small amount of ATP.
Where is pyruvate oxidation in bacteria?
I have the same question. I also need to know which microbe contains the enzyme phospoenolyruvate carboxylase. I am doing a project on this, and I need some answers. I guess we're in this together. :)
Do sparks need oxygen?
Sparks are rapid oxidation. Oxygen is required for oxidation to take place.
Why do fireworks need chemicals with therir own oxygen?
Oxygen is essential to support any combustion; combustion is a chemical process of oxidation.
Do anaerobic organisms need oxygen?
No it does not. Cellular respiration is, in its broadest definition, the process in which the chemical bonds of energy -rich molecules such as glucose are converted into energy usable for life processes. All forms of life except viruses carry out respiration. Oxidation of organic material --- in a bonfire, for example --- releases a large amount of energy rather quickly. The overall equation for the oxidation of glucose is:C6H12O6 + 6O2 ⇒ 6CO2 + 6H2O + energyIn respiration, the process of oxidation is broken down into a large number of steps. These steps are catalysed by enzymes and coenzymes; each step releases a small amount of energy in the form of ATP. This process consists of two main steps: glycolysis, and pyruvate breakdown.Aerobic respiration does not require oxygen. It is the preferred method of pyruvate breakdown. It yields 36 ATP molecules, as well as carbon dioxide, and water. This makes for a total gain of 38 ATP molecules during cellular respiration. This takes place in the mitochondria of the cells.
Which one of the following processes can occur in the absence of oxygen?
Fermentation can occur in the absence of oxygen. This process allows for the production of energy in the form of ATP without the need for oxygen.
What is the oxidation number for MO?
The oxidation number for the compound MO can vary depending on M. In general, oxygen has an oxidation number of -2. Therefore, you would need to know what element M represents in order to determine the oxidation number for MO.
What is oxygen important to your body.?
Your main energy source is the oxidation of hydrogen. Without oxygen you'd have a maximum of about 16 % of your present energy - unfortunately you'd be dead since your brain and your heart both need the oxidation power constantly.

Why pyruvate is converted to lactate when oxygen is not available?
This reaction generates NAD+ from NADH. You need NAD+ for glycolysis, so this conversion (pyruvate to lactate) regenerates one of the reactants needed for glycolysis to continue. You're usually taught that NADH is a source of energy, so getting rid of it when you are energy starved seems counterintuitive. However, when no oxygen is available, you can't use NADH as a source of energy because the electron transport chain is out of commission without oxygen.

What is a property of a combustion reaction?
A combustion reaction is an oxidation reaction - combustion need oxygen; the products are water and carbon dioxide.
