Enzyme Kinetics and Km - correct answer-The reaction catalysed by an enzyme uses exactly the same reactants and produces exactly the same products as the uncatalysed reaction. Like other catalysts, enzymes do not alter the position of equilibrium between substrates and products. Enzyme-catalysed reactions display saturation kinetics: For a given enzyme concentration and for relatively low substrate concentrations, the reaction rate increases linearly with substrate concentration; the enzym...

MCAT Biochemistry Review | Latest Version | 2024/2025 | Graded A+ What is the primary function of the enzyme catalase in cells? Catalase breaks down hydrogen peroxide into water and oxygen, protecting cells from oxidative damage. Explain the role of coenzymes in enzyme-catalyzed reactions. Coenzymes are organic molecules that assist enzymes by providing essential chemical groups or by stabilizing transition states during catalysis. What is the significance of the Km value in en...

How do most enzymes reduce the activation energy needed to move a reaction forward? - ️️Providing an active site most complementary the transition state An enzyme has a mutation within the substrate binding of the coenzyme needed for covalent catalysis. Which of the following is likely to result as a consequence of this mutation? - ️️The enzyme will not be able to form the transition state complex Hemoglobin has the ability to display cooperative binding while myoglobin does not di...

UNIT 1 - Quizzes and Exam, UNE medical biochemistry Unit 1 Test Correctly Answered To Score A+ Which of the following amino acid would not be commonly found in the middle of a an α-helical domain? Proline. It is considered a 'helix breaker' and would not be found in an alpha helix; all other residues are nonpolar hydrophobic and could reside in a transmemebrane domain. Changes in the physiological variables listed below can alter the affinity of hemoglobin for oxygen. Which of the fol...
