Map a Sapling Learning macmillan learning Many enzymes have active sites that contain acidic or basic amino acids. A change in pH can alter the charge on these amino acids as they release or accept H+, changing the charge and function of the enzyme. The human body expends energy to maintain homeostasis, including pH homeostasis, because even a slight change in pH can have serious consequences. This is one reason why enzymes have optimum pH ranges, just as they have optimum temperatures. A deviation from the optimum pH interferes with the enzyme's activity. An example of a graph of enzyme activity (measured by reaction rate) and pH is shown. Place each of the phrases at the appropriate ph value, pH 6 or pH 8 pH 6 pH 8 the enzyme normal ionic bonds may be denatured may be disrupted the enzyme may optimum pH 2 5 6' 7 8 9 10 11 12 13 14 not bind to substrate pH reaction rate is maximal

Explanation / Answer

For this Enzyme pH 6 is extremely low hence following statements will fall for pH 6

1) The enzyme may be denatured

2) The enzyme may not bind to substrate

3) Normal ionic bonds may be disrupted

For this enzyme pH of 8 is Optimal hence following statements will fall under pH 8

1) Optimum pH

2) Reaction rate is Maximal
