Question

Optional: using what you learned in this activity and in pbs, write a hypothesis about the conditions (enzyme, temperature and ph) required for the digestion of proteins in the stomach. outline a controlled experiment that tests your hypothesis. your materials and equipment include: distilled water, pepsin solution, hydrochloric acid (hcl), sodium hydroxide (naoh), ice, beakers, a bunsen burner, thermometer, ph strips, albumin (a protein), biuret reagent (an indicator for proteins), test tubes and various glassware. you may use the internet or resources from pbs to complete this task. be clear about how the results will prove/disprove your hypothesis.

Answer 1

then the hypothesis is proved correct.

Step-by-step explanation:

Answer 2

Stomach enzymes tend to work better in acidic pH.
In order to test this, you could take pepsin solution in HCl, NaOH and water and add the albumen. After regular time intervals, the solutions are tested for the presence of albumen. If the albumen is consumed the fasted in the HCl solution, then the hypothesis is proved correct.
