We often hear people talk about how the body Burns glucose and the others sugars to provide energy but it's not as simple as your stomach just creating raw energy from food explain how on cellular level your body actually breaks down glucose and how the energy ends up in the inner membrane of your mitochondria

*PLEASE HELP WILL MARK, EXTRA POINTS* ​

Answer: The body "burning glucose" is actually a process called cellular respiration. Cellular respiration takes in food and uses it to create ATP, a chemical which the cells uses for energy. This process uses oxygen ans is called aerobic respiration. There are four stages, glycolysis, link reaction, the krebs cycle, and election transport chain. This produces ATP. When they don't get enough oxygen, the cells uses anaerobic respiration, which doesn't require oxygen. When not using oxygen it produces lactic acid, and is not as efficient. Oxidative phosphorylation is the process where energy is harnessed through a series of protein complexes embedded in the inner-membrane of mitochondria to create ATP.

Cellular respiration is a series of metabolic reactions by which cells produce energy (i.e., ATP) from foods (e.g., glucose).

  • Cellular respiration has three main stages: glycolysis, the Krebs cycle, and oxidative phosphorylation.

  • Glycolysis occurs in the cytoplasm, whereas the Krebs cycle and oxidative phosphorylation occur in the mitochondria.

  • The glycolysis reaction uses one glucose molecule to produce 2 ATP, 2 NADH, and 2 pyruvates.

  • Subsequently, these pyruvate molecules are converted to acetyl CoA by a series of reactions that involve decarboxylation, reduction of NAD+ to NADH, and attachment of the coenzyme A.

  • The Krebs cycle then uses acetyl CoA to produce NADH, FADH2, and ATP.

  • In oxidative phosphorylation, electrons move through a series of electron transport carriers, a process that is coupled to the generation of an electrochemical proton (H+) gradient across the inner mitochondrial membrane.

  • Subsequently, this proton gradient is then used to create ATP, the energy coin of the cell, from ADP and phosphate.

  • The synthesis of ATP is catalyzed by a protein complex called ATP synthetase, which is localized in the inner mitochondrial membrane.

In conclusion, cellular respiration is a series of metabolic reactions by which cells produce energy (i.e., ATP) from foods (e.g., glucose).
