Question
Chapter 33.3, Problem 3CC
Summary Introduction
To determine:
What would happen if gastric juice is mixed with crushed food in a test tube.
Introduction:
Gastric juice is secreted by the stomach and it helps in the digestion of the food. Gastric juice contains hydrochloric acid (HCl), mucus, rennin, and pepsin (a protease). It is strongly acidic due to the presence of HCl and has a very low

Experiment: Action of Gastric Proteases (contains pepsin and renin on proteins)
Procedure:
1. Prepare 3 test tubes and place 2 mL boiled egg albumin solution on each tube.
Tube 1: Add 1 mL Pepsin SolutionTube 2: Add 1 mL of Pepsin + 2 drops conc. HClTube 3: add nothing
2. Keep all the test tubes in a beaker with hot water maintained at 40°C, for one hour or longer.
3. Filter the content of each test tube and perform Biuret’s Test by adding 2 mL 10% NaOH and 2 mL dilute CuSO4 solution to each test tube.
Question: What are the possible observations on each test tube? and What is its inference?
