Question

1. the peak of each graph represents the optimum ph for that enzyme. at the optimum ph, the enzyme is the most efficient. identify the optimum ph of each enzyme: a. chymotrypsin: b. cholinesterase: c. pepsin: d. papain: 6. which enzyme is not affected by ph? 7. which enzyme works best under basic conditions? 8. which enzyme works best under neutral conditions? 9. which enzyme is most likely to be found in stomach acid (ph 2)? the graphs to the left show how ph affects four different types of enzymes. use these graphs to answer questions 5 through 9.

Explanation:

Step1: Analyze pepsin graph

Pepsin has peak at pH 2.

Step2: Analyze chymotrypsin graph

Chymotrypsin peaks around pH 8 - 9.

Step3: Analyze papain graph

Papain has flat activity, pH - independent.

Step4: Analyze cholinesterase graph

Cholinesterase active at neutral - basic pH.

Answer:

1. a. chymotrypsin: 8 - 9; b. cholinesterase: 7 - 9; c. pepsin: 2; d. papain: no clear peak
2. papain
3. chymotrypsin
4. papain
5. pepsin
