Question
Chapter 47, Problem 13TYK
Summary Introduction
To review:
Three enzymes that might be likely the suspects for developing protein deficiency leading to nonfunctional enzymes associated with digestions.
Introduction:
The genetic disorder is caused by any defect in the genome sequence. Most of the genetic defect is caused by mutations. Mutations in germ cells are heritable, whereas mutations in the autosomes cause autosomal disorder, which is not heritable.

Introduction to Experiment 2: Protein Digestion by Pepsin
In this experiment, we will look at for evidence of protein digestion using albumin, a protein, and Biuret reagent. Biuret reagent is used to test for the presence of proteins, or more specifically, peptide bonds. When long polypeptide chains are present the solution will turn violet, and when shorter polypeptide chains are present the solution will turn a lighter pink color.
What is/are the end product(s) of protein digestion? Amino acids
What is the purpose of the enzyme pepsin? It helps in the digestion of proteins by breaking down the peptide bonds between amino acids into smaller peptides
If protein digestion has occurred, will the solution be violet or pink (choose one)?
Hypotheses/Predictions (See Methods section for details):
What color do you expect the solution to turn when the P tubes are mixed with Biuret solution and why?
P1
P2
P3
P4
The least protein digestion (or none at all) will take place in tubes…
What is the function of an enzyme? Name three important enzymes that are used in the digestive process in human body and describe their functions.
Describe the role of feedback inhibition in controlling amino acid synthesis
