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+
What else can I help you with?
What are the two other names for Krebs cycle?
Citric Acid Cycle TCA Cycle (tricarboxcylic acid cycle).
What two molecules combine to produce citric acid in the citric acid cycle?
Acetyl-CoA and oxaloacetate combine to produce citric acid (or citrate) in the citric acid cycle. This is the first step in the cycle, also known as the condensation step.
Pyruvate is the end product of?
glycolysis. It is a 3-carbon compound that can be further metabolized in the presence of oxygen to enter the citric acid cycle or converted to lactate or ethanol in the absence of oxygen through fermentation.
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.
Why is the kerbs cycle also known as the citric acid cylce?
The Krebs cycle is also known as the citric acid cycle because citric acid is the first compound formed in the cycle. The cycle then proceeds to harvest energy through a series of chemical reactions involving citric acid and other molecules, ultimately producing ATP for cellular energy.
What is the citric acid cycle also known as?
Krebs cycle (aka citric acid cycle, aka tricarboxylic 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.
Is the citric acid cycle aerobic or anaerobic?
The citric acid cycle, also known as the Krebs cycle, is an aerobic process that occurs in the mitochondria of cells. It requires oxygen to function efficiently and produce energy in the form of ATP.
What are the two other names for Krebs cycle?
Citric Acid Cycle TCA Cycle (tricarboxcylic acid cycle).
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 two molecules combine to produce citric acid in the citric acid cycle?
Acetyl-CoA and oxaloacetate combine to produce citric acid (or citrate) in the citric acid cycle. This is the first step in the cycle, also known as the condensation step.
Pyruvate is the end product of?
glycolysis. It is a 3-carbon compound that can be further metabolized in the presence of oxygen to enter the citric acid cycle or converted to lactate or ethanol in the absence of oxygen through fermentation.
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.
Why is the Citric Acid cycle called a cycle?
The Citric Acid cycle is called a cycle because it is a series of chemical reactions that regenerates its starting molecule, oxaloacetate, at the end. This allows the cycle to continue repeatedly as long as there are substrates available.
What is another way to say Calvin cycle?
C6 cycle, Citric/Citric Acid cycle
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 organelle does the citric acid cycle occur?
The citric acid cycle, also known as the Krebs cycle, occurs in the mitochondria of eukaryotic cells.
