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.

A reaction mixture (200μl) was prepared with the same formula optimized for the enzyme activity assay (0.1 M Tris-HCl ph 8, 0.1 M KCI, 25 mM NaCl, 0.25 mM ATP, and two units of inorganic yeast pyrophosphatase) with 10 µM of the sample molecule. The reaction mixture was incubated for 20 minutes at ambient temperature. Enzymatic reaction was triggered by addition of the substrate B (0.2 mM) and the absorbance of the product was monitored at 290 nm for 10 minutes. Six out of 15 sample molecules showed appreciable inhibition at 10 μM (Figure 5). Three of the molecules, A3, A6, and A7 exhibited more than 50% inhibition of the enzyme activity and were further diluted to find the minimal…arrow_forward

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_forward
