EVOLUTION LINK The reactions of glycolysis are identical in all organismsprokaryotes, protists, fungi, plants, and animalsthat obtain energy from glucose catabolism. What does this universality suggest about the evolution of glycolysis?
6. Cycle of tricarboxylic acids (TCA):• importance for cellular metabolism;• intracellular localization of TCA enzymes;• sequence of TCA reactions;• TCA enzymes and coenzymes;• substrate phosphorylation reactions in TCA;• decarboxylation reactions in TCA;• enzymes and coenzymes in dihydrogen reactions in TCA;• mechanisms of regulation of TCA.
20. A hoax, perhaps? The citric acid cycle is part of aero-bic respiration, but no O 2 is required for the cycle. Explainthis paradox.
1- ATP consider as an important molecule in metabolism, because : A) It is one of the four building blocks for DNA synthesis.B) It provides energy coupling between exergonic and endergonic reactions.C) Its terminal phosphate group contains a strong covalent bond that, when hydrolyzed, releases free energy.D) Its hydrolysis provides an input of free energy for exergonic reactions.E) Its terminal phosphate bond has higher energy than the other two. 2- How many ATP yield from complete oxidation of glucose to carbon dioxide and water: A) 38 B) 32C) 2D) 8E)24
1- The substrate used in the last step of glycolysis is: A) Glyceraldehyde 3-phosphateB) PyruvateC) 1, 3-bisphosphoglycerateD) Phosphoenolpyruvate 2- One of cellular processes is breaking down large molecules into smaller ones, which term most precisely describes this: A) catalysisB) dehydrationC) metabolismD) anabolismE) catabolism
11. Metabolism include catabolic and anabolic reactions. Which of the followings describe anabolic reactions? a) Smaller molecules are generated from the breakdown of larger molecules and nutrients b) Larger molecules are synthesized from small catabolic products c) One molecule transfers a monomer to another molecule to build components of cell d) Anabolic reactions are main source of harvesting electrons and production of ATP
Choose False during an enzyme catalyzed reaction. Substrate concentration is typically much larger than that of enzymes. The rate of enzymatic reaction is related to the concentration of ES complex. Velocity of reaction reaches a plateau above certain substrate concentration. Velocity of reaction is linearly dependent on a substrate concentration. Maximum velocity is related to the number of catalytic turnovers in the unit time.
1. Explain why the maximum initial reaction rate cannot be reached at low substrate concentrationsPredict or describe the absorbance or enzyme activity at: pH = 2 pH = 14 Explain your predictions 2. Explain why the maximum initial reaction rate cannot be reached at low substrate concentrations.
1. Provide the best coenzyme(s) for each step shown below. Give a 1–2 sentence rationale for your choice. 2. Reaction (C) can require multiple coenzymes, or the enzyme may only require one. Briefly describe how the reaction that uses only one coenzyme works. Be specific about the mechanism.
I'm confused about glycolysis and gluconeogenesis. Question: What is the function of glyceraldehyde 3-phosphate dehydrogenase? Is it because of -> The incorporation of a phosphate from ATP and reduction of glyceraldehyde 3-phosphate or ->The incorporation of phosphate from inorganic phosphate and reduction of glyceraldehyde 3-phosphate. or -> The incorporation of phosphate from inorganic phosphate and oxidation of glyceraldehyde 3-phosphate
