Question

part of digestive system mouth stomach small intestine large intestine ph range 6.5 - 7.5 1.5 - 4.0 4.0 - 7.0 4.0 - 7.0 enzymes and ph 20 multiple choice 1 point which enzyme works best in an acidic environment? chymotrypsin pepsin neither of the enzymes both chymotrypsin and pepsin clear my selection 21 multiple choice 1 point which enzyme works best in a slightly basic environment? chymotrypsin pepsin neither of the enzymes both chymotrypsin and pepsin

Explanation:

1. For question 20: Pepsin works best in an acidic environment. The graph for pepsin shows high relative - activity at a low pH (acidic).
2. For question 21: Chymotrypsin works best in a slightly basic environment. Its graph shows high relative - activity at a pH around 8 - 9 which is slightly basic.

Answer:

1. pepsin
2. chymotrypsin
