succinyl-CoA
2 June 2004Succinyl-CoA is a substrate for the citric acid cycle (or Krebs cycle) in the cell.
Citric acid cycle (or Krebs cycle or TCA cycle)
The citric acid cycle (or Krebs cycle or TCA cycle) takes place within the mitochondrial matrix. In this cycle, pyruvic acid generated from glycolysis is converted into acetyl coenzyme A (acetyl CoA) by losing a carbon dioxide molecule. It then combines with oxaloacetic acid to form citric acid, a six-carbon molecule.
In total, it loses 2 CO2 molecules and 4 (...) -
uracil
17 October 2005Definition: Uracil is a pyrimidine base (nitrogenous base) and constituent of nucleotides and as such one member of the base pair A-U (adenine-uracil). It is normally found in RNA but not DNA.
Uracil is one of the four major RNA nucleobases, and replaces the DNA base thymine. Similar to thymine, uracil can form a base pair with adenine via two hydrogen bonds, but it lacks the methyl group present in thymine.
Uracil is not normally incorporated into DNA and is only very rarely observed in (...) -

ATP
4 February 2006ATP is produced in two ways: oxidative phosphorylation and glycolysis
OXPHOS system and oxidative phosphorylation
The major pathway in mammalian cells is oxidative phosphorylation of adenosine diphosphate, in a reaction that results in reduction of oxygen by the electron transfer system of mitochondria.
glycolysis and the glycolytic pathway
The second is the glycolytic pathway, which can generate ATP in the absence of oxygen using glucose derived either from body fluids or from the (...)
