Metabolic Pathways

Metabolic pathways are sequenced reactions. Some are catabolic which produce energy in some phosphate groups.
3 Metabolic pathways:
1. Occurs in the cytoplasm also known as Glycolysis. All organisms undergo glycolysis in all cells (animals, plants and bacteria). NADH.
2. occurs in mitochondrial matrix cytoplasm within the mitocondria. Only Eukaryotic cells have mitocondria. (Kreb's cycle, Citric Acid cycle, Tri-carboxylic acid (TCA)). NADH and FADH2.
3. Occurs in mitocondrial Cristae (inner membrane). ETS = Electron Transport System. All about the transfer of electrons. ATP.
Glucose is cut in half in Glycolysis.
