Question

1. a student completed a series of experiments and found that a particular digestive enzyme works best at a ph of 8.0 and a temperature of 37°c. based on this information, which procedure would have the least effect on the rate of protein digestion? (a) adding more protein (b) adjusting the ph to 6.0 (c) decreasing the temperature to 25°c (d) increasing the amount of light (e) increasing the amount of water

a. procedure a
b. procedure e
c. procedure c
d. procedure d

1. the effect of ph on a certain enzyme is shown in the graph.

rate of enzyme activity
0 1 2 3 4 5 6 7 8 9 10 11 12 13
ph
at what ph would the enzyme be most effective?
a. above 10
b. between 8 and 10
c. between 5 and 7
d. below 5

Explanation:

The graph shows the relationship between pH and the rate of enzyme - action. The peak of the curve represents the optimal pH at which the enzyme is most effective. By observing the graph, the peak occurs between pH 8 and 10.

Answer:

B. between 8 and 10
