In the human digestive system, the enzyme pepsin is present in acidic areas, while the enzyme trypsin is present in less acidic areas. Which of these statements most likely describes a difference in how they function? Pepsin functions optimally at a lower pH level than trypsin
Trypsin functions optimally at a lower pH level than pepsin
Pepsin functions optimally at a lower temperature than trypsin
Trypsin functions optimally at a lower temperature than pepsin
