Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial ...

Researchers have new insights into the citric acid cycle: Certain bacteria can use this central metabolic pathway 'backwards', but to do so they must have very high concentrations of the enzyme ...

While testing a theory about how sugars formed on early Earth, researchers stumbled upon reaction conditions that produce tartrates, molecules closely related to others in a key metabolic cycle found ...
