Harvesting Energy 23 March 2025 15:05 Cellular respiration is the process by which individual cells break down organic compounds, such as glucose and release energy in the form of ATP . It occurs in the cells of both autotrophs and heterotrophs. The reactions of cellular respiration can be grouped into three main stages and an intermediate stage: 1. 2. 3. 4. Glycolysis Pyruvate oxidation Citric acid cycle Oxidative phosphorylation C6H12O6+6O2⟶6CO2+6H2O+Energy Lysis (splitting) of glucose ATP (adenosine triphosphate): An ATP molecule is like a rechargeable battery: its energy can be used by the cell when it breaks apart into ADP (adenosine diphosphate) and phosphate, and then the “worn-out battery” ADP can be recharged using new energy to attach a new phosphate and rebuild ATP. ADP can be further reduced to AMP (adenosine monophosphate and phosphate, releasing additional energy. As with ADP "recharged" to ATP, AMP can be recharged to ADP. Glycemia (glucose homeostasis): Process Cellular Location Presence of Oxygen Substrate or oxidative phosphate Glycolysis Pyruvate oxidation Citric Acid Cycle Electron Transport Chain/ Chemiosmosis
