Based on Figure 8.17b, what are the approximate optimal pH values for pepsin and trypsin, respectively?

  • A: Pepsin: pH 2; Trypsin: pH 8
  • B: Pepsin: pH 7; Trypsin: pH 2
  • C: Pepsin: pH 8; Trypsin: pH 2
  • D: Pepsin: pH 4; Trypsin: pH 6

Explanation

The graph clearly shows that pepsin's activity peaks at a pH of approximately 2, while trypsin's activity peaks at a pH of approximately 8. These are their respective optimal pH values.
