Oxidation

I. cellular Respiration A. How Cells Acquire ATP 1. Cellular away respiration: Includes the various metabolic pathways that break down carbohydrates to mother ATP. a. Cellular respiration requires oxygen (aerobic process) and gives off carbon dioxide. 2. C6H12O6 + 6O2?6CO2 + 6H2O + sinew 3. Glucose is oxidate and oxygen is reduced. a. oxidation is loss of negatrons and reduction is make believe of electrons. 4. A hydrogen atom consists of a hydrogen ion centre of attention an electron (H+ + e-). So, when hydrogen atoms argon removed from glucose, so are electrons. 5. Glucose is a high- muscularity molecule, carbon dioxide and water are low zipper molecules. This process is exergonic and drives ATP synthesis which is an endergonic reaction. 6. The pathways of cellular respiration on the wholeow the strength within a glucose molecule to be released loath so that ATP can be produced gradu ally. 7. Cells would lose a lot of energy as heat if glucose breakdown occurred all at once. 8. Breakdown of glucose yields synthesis of 36 or 38 ATP (equivalent to about 39% of the energy that was available in glucose). B. NAD+ and hysteria 1. Each metabolic reaction in cellular respiration is catalyzed by its own enzyme. 2. NAD+ and hysteria: Coenzymes of redox. 3.

As a metabolite is oxidized, NAD+ accepts 2 electrons and a H+ ion. This makes NADH. 4. electrons received by NAD+ and FAD are high- energy electrons and are usually carried to the electron transport system. 5. NAD+ is a coenzyme of oxidoreduction since it two accepts and gives up electrons. 6. FAD is another coenzyme of oxidation-red uction that can replace NAD+. FAD accepts 2 ! electrons and both H+ ions to become FADH2. Cells need a limited sum of these coenzymes because they constantly recycle. 7. The oxidation of glucose by removal of hydrogen atoms involves intravenous feeding phases: a. Glycolysis b. Preparatory (Prep) Reaction c. Citric Acid unit of ammunition d. Electron Transport Chain...If you want to get a wide of the mark essay, coiffure it on our website: OrderEssay.net
