The citric acid cycle does not directly utilize oxygen, however it is still necessary in order for it to proceed. The reason for this is that in order for NADH to be reduced back into NAD+, oxygen must be present. If NAD+ is not regenerated, the cycle can't proceed, thus fermentation evolved.
This is correct except for that NADH must be oxidized to NAD+, not reduced. Reduction of NAD+ results in NAHD + H+

Why is the citric acid cycle called an anaerobic cycle when it does not use oxygen?
The fact that it does not use oxygen is precisely why it is anaerobic. Anaerobic means without oxygen. If it did use oxygen, it'll be called aerobic.
What are the inputs and outputs of the citric acid cycle?
The net inputs for citric acid cycle are Acetyl CoA, NADH, and ADP. The Net outputs for the citric acid cycle are ATP, NAD, and carbon dioxide.
What are the intermediates in the citric acid cycle?
There are 4: oxaloacetate, malate, fumarate, and succinate.
Where does citric acid come from?
How is citric acid produced? Good question! citric acid is produced in a cycle called Krebs Cycle. As Pyruvic acid enters the mitochondrion, carbon is removed,forming co2, and electrons are removed, changing NAD+ to NADH. Co-enzyme A joins the 2-carbon molecule, forming acetyl-CoA. Acetyl-CoA then adds the 2 carbon acetyl group to a 4-carbon compound, forming citric acid. Before the Krebs cycle there is the glycolysis cycle. In this cycle the product is the pyruvic acid. So after that the Krebs cycle or the Citric acid cycle starts, which starts off with pyruvic acid. Then the election transport cycle. This might be confusing but if you see a diagram of these cycles, that will help you a lot! hi my name is austin im looking for more firends so if you see this add me on facebook @ sexyzigrat@hotmail.com :)
What are the two other names for Krebs cycle?
Citric Acid Cycle TCA Cycle (tricarboxcylic acid cycle).
What stage of cellular respiration follows glycolysis in the presence of oxygen?
If there is no oxygen present, then the cell does either alcohol or lactic acid fermentation. If oxygen is present, the citric acid cycle follows glycolysis, with oxidative phosphorylation following the citric acid cycle.
What is the citric acid cycle also known as?
Krebs cycle (aka citric acid cycle, aka tricarboxylic acid cycle)
Why is the Citric Acid cycle called a cycle?
Because it goes around and around as in a unicycle wheel.
How did the citric acid cycle get its name what is the origin of citric acid cycle?
The conguate base of citric acid - citrate - is an important intermediate in the cycle. This is where the name "Citric Acid Cycle" comes from. It is also known as the Tricarboxylic Acid Cycle - as it involves 3 carbon acids, or the Krebs Cycle after Hans Adolf Krebs - who developed the complexities of the cycle.
What are the Outputs of the citric acid cycle?
The net inputs for citric acid cycle are Acetyl CoA, NADH, and ADP. The Net outputs for the citric acid cycle are ATP, NAD, and carbon dioxide.

What is another way to say Calvin cycle?
C6 cycle, Citric/Citric Acid cycle
Where do reactions of the Citric Acid cycle occur in?
Citric acid cycle occurs in the inner matrix of the mitochondria.

What pathways are located in the mitochondria?
Respiratory pathways, energy producing, TCA-cycle (citric acid cycle, Krebs cycle) and many other related pathways.Cf. 'Related links' on Mitochondrial Functions
