The enzyme trypsin aids in protein digestion in the small intestine. The relative activity of trypsin at different $$\(\mathrm{pH}\)$$ values is shown in Figure 1. Which of the following statements best explains the activity levels of trypsin shown in Figure 1?
A.
The small intestine releases inhibitor molecules that block the activity of trypsin unless it is at its optimum \(\mathrm{pH}\).
B.
The number of effective collisions between trypsin and its substrate increase at higher \(\mathrm{pH}\) values.
C.
As \(\mathrm{pH}\) values increase, the substrate concentration decreases, leading to an eventual decline in the rate of the trypsin-catalyzed reaction.
D.
At extremely low \(\mathrm{pH}\) values, trypsin is denatured and cannot function efficiently.
