The effect of temperature on the action of pepsin, a protein-digesting
enzyme present in stomach fluid, was tested. In this investigation,
20 milliliters of stomach fluid and 10 grams of protein were placed im
each of five test tubes. The tubes were then kept at different tempera-
tures. After 24 hours, the contents of each tube were tested to deter-
mine the amount of protein that had been digested. The results are
shown in the table below.

The dependent variable in this investigation is the
(1) size of the test tube
(2) time of digestion
(3) amount of stomach fluid
amount of protein digested
Directions (47-48): Using the information in the data table, construct a line graph on
the grid on page 15, following the directions below.
15) Mark an appropriate scale on each axis.
Plot the data on the grid. Surround each point with a small circle and connect th
points.

17 If a sixth test tube identical to the other tubes was kept at a temperature of 30°C for
24 hours, the amount of protein digested would most likely be
