15. Cellular Respira on and Metabolism Overview of Cellular Respira on: Cellular breathing is a metabolic process that converts glucose into ATP (adenosine triphosphate), the energy forex of the cellular. It includes three foremost ers: 1. Glycolysis: Occurs in the cytoplasm, wherein glucose is broken down into two molecules of pyruvate, producing a net beneﬁt of two ATP and 2 NADH. 2. Krebs Cycle (Citric Acid Cycle): Takes place in the mitochondria, in which acetyl-CoA is oxidized, producing 2 ATP, 6 NADH, and a couple of FADH2 according to glucose molecule. 3. Electron Transport Chain (ETC): Also in the mitochondria, electrons from NADH and FADH2 are surpassed through protein complexes, riding the produc on of about 34 ATP molecules through oxida ve phosphoryla on. ATP Produc on and Energy Storage: ATP stores strength in its excessive-energy phosphate bonds, which may be conveniently broken to gasoline cellular strategies. The majority of ATP is produced all through the ETC, in which oxygen acts as the very last electron acceptor, forming water. Metabolic Pathways in Cells: Metabolism encompasses all chemical reac ons in cells, together with catabolic pathways that damage down molecules to launch electricity and anabolic pathways that construct complex molecules from less complicated ones, the use of energy. Cellular respiratory is cri cal for energy manufacturing, impar ng ATP that powers mobile sports and maintaining existence.
