Can you explain how 36 ATP is forned in cellular respiration in eukaryotes? It depends on the cell's efficiency and therefore fluctuates in the maximum production of ATP. Direct link to isaac22perez22's post The process of oxidative , Posted 6 years ago. start superscript, 2, comma, 3, comma, 4, end superscript. Did you mean the opposite of what you wrote? C. oxidation of pyruvate to acetyl CoA and the citric acid cycle That situation does not change because of a mechanism that we call respiratory control. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP. In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. It is just one extra phosphate group in NADPH, the rest of the molecule is identical. B. C. It was converted to urine and eliminated from the body. In aerobically respiring eukaryotic cells the ETC is composed of four large, multiprotein complexes embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them. (Neglect air resistance. Overview of oxidative phosphorylation. Oxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. B. how electron transport can fuel substrate-level phosphorylation C. synthesis of acetyl CoA from pyruvate Eventually, the electrons are passed to oxygen, which combines with protons to form water. B. the oxidation of pyruvate to acetyl CoA MB chapter 9 Flashcards | Quizlet When the NAD+ bonds with a hydrogen the electrons are hogged by the very negative atoms like when Sal was talking about glucose. Does the formation of H20 release ATP as a by product that is then regenerated? As electrons move energetically downhill, the complexes capture the released energy and use it to pump H, Like many other ions, protons can't pass directly through the phospholipid bilayer of the membrane because its core is too hydrophobic. B. have a lot of oxygen atoms. In mitochondria, exergonic redox reactions a. are the source of e 0% Glucose is the primary fuel for cellular respiration. B. food glycolysis citric acid cycle NADH ATP The electron in each hydrogen atom is completely transferred to the oxygen atom, and each hydrogen atom has a net charge of +1. Image of the electron transport chain. Sorry I know it may seem like a stupid question but I find myself confused on this stage. First, however, the pyruvate (1) loses a carbon, which is given off as a molecule of CO2, (2) is oxidized to form a two-carbon compound called acetate, and (3) is bonded to coenzyme A. Why is glycolysis considered to be one of the first metabolic pathways to have evolved? 18-24 How would anaerobic conditions (when no O2 is present) affect the rate of electron transport and ATP production during oxidative phosphorylation? In chemiosmosis, what is the most direct source of energy that is used to convert ADP + i to ATP? In eukaryotes, this step takes place in the matrix, the innermost compartment of mitochondria. In these steps, electrons from glucose are transferred to small molecules known as electron carriers. It's being reduced because NAD+ is made up of carbon, hydrogen, nitrogen, oxygen and phosophorus atoms and all of these are very electronegative except for hydrogen.
