Question

question 24 of 25 reaction rate) and ph is shown. place each of the phrases at the appropriate ph value, ph 6 or ph 8. answer bank the enzyme may not bind to substrate optimum ph reaction rate is maximal the enzyme may be denatured normal ionic bonds may be disrupted

Explanation:

From the graph, the enzyme activity peaks around pH 8. At the optimum pH, the reaction rate is maximal. At pH values away from the optimum, normal ionic bonds may be disrupted, the enzyme may not bind to the substrate, and the enzyme may be denatured. Since the optimum is around pH 8, for pH 6 (non - optimum lower pH): the enzyme may not bind to substrate, the enzyme may be denatured, normal ionic bonds may be disrupted. For pH 8 (optimum pH): optimum pH, reaction rate is maximal.

Answer:

pH 6: the enzyme may not bind to substrate, the enzyme may be denatured, normal ionic bonds may be disrupted
pH 8: optimum pH, reaction rate is maximal
