What else can I help you with?
Is the first metabolite of the Krebs cycle citrate?
Since Krebs is a cycle, there is a pretty good argument that there is no "first metabolite". However, because citrate is a condensation product of OAA and acetyl-CoA, and acetyl-CoA is typically what is feeding in to the Krebs cycle, citrate could be considered the "first metabolite"
How is water formed as a by-product of the Krebs cycle?
The Krebs Cycle generates 3 molecules of NADH with 3 H+ ions as well as one seperate molecule of FADH2. Both are shuttled to the electron transport chain in the inter-mitochondrial membrane. The NADH is oxidized as its electrons are moved through the first protein in the chain. Ubiquinone (the coolest name in all of biology) accepts the electrons from FADH2 also oxidizing it. At the end of the chain, the final protein passes the electrons (H+ ions) onto half of an O2 molecule forming one molecule of water.
After ATP is used what happens to the pyruvate molecule in glycolysis?
The two molecules of pyruvic acid (pyruvate) produced from glycolysis (glucose, glucose-6-phosphate, fructose-6-phosphate, fructose 1,6 biphosphate.... pyruvate) turn into acetyl coenzyme A (acetyl CoA). Acetyl CoA enters the Krebs cycle, reacting with oxaloacetate to form citrate [which is why the Krebs cycle is known as the citric acid cycle].
What is the best rug material?
The best material for rug is the most simple material: wool . It is the first material used to wave the rugs and also the most resistant one
What type of cell or structure is the first stage of every sexual life cycle?
zygote
What is the first acid produced in Krebs cycle?
Citrate

In cellular respiration glycolysis follows the Krebs cycle true or false?
False. In cellular respiration, glycolysis occurs before the Krebs cycle. Glycolysis is the first step in breaking down glucose to produce energy. The Krebs cycle follows glycolysis in the process of cellular respiration.
Who is the Krebs cycle named after?
The Krebs cycle is named after its discoverer, Sir Hans Krebs, a German-born British biochemist. Krebs first described this series of chemical reactions that occur in the mitochondria of cells in 1937.
What is the cycle about the reactions that make up the Krebs cycle?
The first reactant and last product are the same.
What is cycle about the reactions that make up the Krebs cycle?
The first reactant and last product are the same.
Where did the first carbon come from in the Krebs cycle?
If by "first carbon" you mean the first CO2 released in the cycle then the answer is, from OAA. NOT from acetyl CoA.
What is the name of the first form in the Krebs cycle?
ATP (Adenosine Triphosphate) ?
The stages of aerobic respiration are?
First stage is Glycolysis pyruvate is then turned into Acetyl CoA and enters the Krebs Cycle Second stage is Krebs Cycle Third stage is Electron transport chain
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 is a 6 carbon compound formed during the Krebs cycle?
A 6 carbon compound formed during the Krebs cycle is citrate. It is the first product formed in the cycle when acetyl-CoA combines with oxaloacetate.
Does glycolosis or Krebs cycle come first?
Glycolysis evolved first. Cells of all types of organisms are able to carry out glycolysis. The Krebs cycle arose after photosynthetic organisms began adding oxygen to the atmosphere because Krebs cycle requires oxygen and glycolysis does not.
