Exam points
- 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
3.2.B—Explain how the cellular environment affects enzyme activity question 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
Based on Figure 1, explain how the binding of amino acid A to enzyme 1 is regulated by
amino acid B.
