Question
Chapter 7.6, Problem 1CS
Summary Introduction
To predict: The way in which a mutation in the β subunit of ATP synthase would affect ATP synthesis.
Introduction: ATP synthesis in cells occurs with the help of the enzyme, ATP synthase as it combines an inorganic phosphate molecule with ADP. A mutation in the β subunit of ATP synthase has been identified. This only affects conformation 3.

- IDENTIFICATION: 1.In this model, the substrate still needs to fit into the enzyme like a key, but instead of simply fitting into the "keyhole," some type of modification is induced in the substrate, enzyme, or both. 2.Creatinine Kinase found in skeletal and heart muscle 3.Creatinine Kinase found in heart muscle 4.Creatinine Kinase found in the brain 5. To overcome an energy barrier between reactants and products, energy must be provided to get the reaction started. This energy, which is recovered as the reaction proceeds, is called: A. Potential energy B. Initiation energy C. Reaction energy D. Activation energy 6. The active site of the enzyme and substrate have complementary structures, hence they fit together as a key fits a lock. 7. TRUE or FALSE. Increase concentration of substrate, Increase enzyme action. 8. TRUE or FALSE. Decrease concentration of enzyme, Increase enzyme action.arrow_forwardFill in the blanks.: Write Cif only statement A is correct, Hif only statement B is correct, E if both statements are correct, M if both statements are incorrect.
