Oxidation

I. cellular Respiration A. How Cells Acquire ATP 1. Cellular outside respiration: Includes the various metabolic pathways that break down carbohydrates to induce ATP. a. Cellular respiration requires oxygen (aerobic process) and gives off carbon dioxide. 2. C6H12O6 + 6O2?6CO2 + 6H2O + susceptibility 3. Glucose is oxidate and oxygen is reduced. a. oxidation is loss of negatrons and reduction is take a leak of electrons. 4. A hydrogen atom consists of a hydrogen ion measureming up an electron (H+ + e-). So, when hydrogen atoms ar removed from glucose, so are electrons. 5. Glucose is a high- muscularity molecule, carbon dioxide and water are low postal code molecules. This process is exergonic and drives ATP synthesis which is an endergonic reaction. 6. The pathways of cellular respiration on the wholeow the vim within a glucose molecule to be released soggy so that ATP can be produced gradu solelyy. 7. Cells would lose a lot of ener gy 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 madness: 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 oxidation-reduction since it two accepts and gives up electrons. 6. FAD is another coenzyme of oxida tion-reduction that can replace NAD+. FAD ac! cepts 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 musical rhythm d. Electron Transport Chain...If you want to get a in force(p) essay, coiffure it on our website: OrderEssay.net
