When glucose goes through the steps of cellular respiration, the overall process can be summarized as the oxidation of glucose. Question 4 options: True False
Electron Transport Chain
The electron transport chain, also known as the electron transport system, is a group of proteins that transfer electrons through a membrane within mitochondria to create a gradient of protons that drives adenosine triphosphate (ATP)synthesis. The cell uses ATP as an energy source for metabolic processes and cellular functions. ETC involves series of reactions that convert redox energy from NADH (nicotinamide adenine dinucleotide (NAD) + hydrogen (H)) and FADH2(flavin adenine dinucleotide (FAD)) oxidation into proton-motive force(PMF), which is then used to synthesize ATP through conformational changes in the ATP synthase complex, a process known as oxidative phosphorylation.
Metabolism
Picture a campfire. It keeps the body warm on a cold night and provides light. To ensure that the fire keeps burning, fuel needs to be added(pieces of wood in this case). When a small piece is added, the fire burns bright for a bit and then dies down unless more wood is added. But, if too many pieces are placed at a time, the fire escalates and burns for a longer time, without actually burning away all the pieces that have been added. Many of them, especially the larger chunks or damp pieces, remain unburnt.
Cellular Respiration
Cellular respiration is the cellular process involved in the generation of adenosine triphosphate (ATP) molecules from the organic nutritional source obtained from the diet. It is a universal process observed in all types of life forms. The glucose (chemical formula C6H12O6) molecules are the preferred raw material for cell respiration as it possesses a simple structure and is highly efficient in nature.

Oxidation means the reaction involved with the gain of oxygen and loss of an electron. Glucose is a very important carbohydrate and source of energy. Glycolysis takes place in the cytoplasm of the cell and all other reaction of cellular respiration takes place in the mitochondria. Pyruvate oxidation, citric acid cycle, and oxidative phosphorylation are the important steps of cellular respiration.
In the oxidative phosphorylation, the electrons generated by NADH or FADH2 are travel by series of electron carriers in the electron transport chain (ETC) and finally to ATP synthase where the enzyme ATP synthase converts ADP and phosphate into the ATP by the process of chemiosmosis. The oxidative phosphorylation takes place in the inner mitochondrial membrane
