  • predict reaction-rate changes from substrate or product concentration and temperature
  • distinguish competitive and noncompetitive inhibition from binding site and response
  • interpret enzyme activity data to estimate optima, inhibition or metabolic effects

AP Biology 3.2 B Explain How the Cellular Environment Affects Enzyme Activity Questions question 1

[Maximum number: 1]

Figure 1 shows the reactions of the metabolic pathway used to synthesize amino acid B from amino acid A in cells.

Figure 1. Synthesis of amino acid B from amino acid A

Figure 1. Synthesis of amino acid B from amino acid A

Based on Figure 1, explain how the binding of amino acid A to enzyme 1 is regulated by amino acid B.
