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 ...

Cells generate energy from the controlled breakdown of food molecules. Learn more about the energy-generating processes of glycolysis, the citric acid cycle, and oxidative phosphorylation.

This enzyme links the two stages of cellular respiration: glycolysis and the citric acid cycle. In doing so, pyruvate dehydrogenase helps regulate the metabolic plasticity of cells. The ...
