Rank from the first to the last steps to describe the correct order of events of glycolysis. Glucose 000000 k First phosphorylation: Glucose is phosphorylated by ATP, First Glyceraldehyde- 3-phosphate COO-P -NAD This reaction happens twice, once for each glyceraldehyde- 3-phosphate 1.3- bisphosphoglycerate P-000-P+ NADH +ADP Oxidation: Glyceraldehyde-3-phosphate is phosphorylated and oxidized by NAD to yield NADH and 1 bisphosphoglycerate, which then donates a PI to ADP, producing ATP. Fructose-1,6-bisphosphate P-000000-P + ADP 1 V Dihydroxyacetone- 3-phosphate Y Cleavage: The six-carbon fructose-1,6- bisphosphate is split, and two three-carbon molecules are formed. Glucose-6-phosphate 000000-P + ADP Rearrangement Fructose-6-phosphate OOOOOO-P P Second phosphorylation: The carbon atoms in glucose-6-phosphate are rearranged, and the molecule is then phosphorylated by another ATP. 3-phosphoglycerate COO-P+ 2-phosphoglycerate 000 Rearrangement Phosphoenolpyruvate COO +ADP Reset Help Pyruvate 000 - ATP This reaction happens twice, once for each 3-phosphoglycerate ATP synthesis: The carbon atoms in 3-phosphoglycerate are rearranged to form phosphoenolpyruvate, which donates a P to ADP, yielding ATP and pyruvate.

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.
