Cellular respiration is a process our body completes millions of times per day. Cellular respiration is the process of creating ATP (energy) from ADP and a phosphate inorganic by using the energy released from breaking apart a glucose molecule. ATP is the energy that we use everyday and without it, we would not be able to perform everyday tasks. The equation representation is glucose and oxygen yields carbon dioxide and water and energy (C6H12O6 + 6O2 → 6H2O + 6CO2 + ATP). The oxygen gets reduced into water and the glucose gets oxidized into carbon dioxide. Organisms like bacteria, plants, animals, and fungi use cellular respiration by taking in food which they convert into glucose and then break down into pyruvate (which is a 3 carbon molecule). …show more content…
The next part is the Kreb’s cycle which finishes breaking down all of the bonds in glucose to release the electrons and create ATP through substrate-level phosphorylation. Substrate-level is process that consists of binding a phosphate group to an intermediate and then breaking that bond in order for it to bind to ADP, which will then create ATP. CO2 is released through this process. NADH and FADH2, which are electron carriers, take the electrons from the broken bonds in the broken up glucose and transport them to the electron transport chain which pumps H+ ions out of the inner matrix and then moves the electrons along until they bond with oxygen which then forms water. Oxygen is imperative to this step. The H+ ions finally move back through the membrane using ATP synthase as a channel. The flow of H+ ions through this channel creates enough energy to put ADP and Pi together into ATP. Overall, this process of the electron transport chain, Kreb’s cycle, and glycolysis creates 30-32 ATP molecules. The ATP is used for powering many reactions in the body and keeps us
