Introduction:
Digestion is breakdown of larger food particles into smaller food particles. The digestive system hydrolyzes macro molecules which can be carbohydrates, proteins and fats present in the food into their respective subunit and absorb these subunit molecules and eliminate the waste.

During digestion, the presence of proteases makes proteins be digested first. Given this occurrence, what is the catalytic rc
of the proteases? (Reference: https://www.britannica.com/science/proteolytic-enzyme)
It does not do anything directly to the digestion process of proteins
It boosts the digestion process to match the digestion of all food matter
It slows down the digestion process of other food matter
It speeds up the digestion of proteins ingested by the organism

Introduction to Experiment 3: Lipid Digestion by Lipase
In this experiment, we will investigate lipid digestion. Remember that lipids include fats, so the two terms are often used interchangeably. To do this, we will use litmus cream, which is a mixture of cream and litmus. Cream contains triglycerides (neutral fats). Litmus is a pH indicator. Purple indicates a neutral pH. Pink indicates an acidic pH. Blue indicates a basic pH.
How do bile salts act on a mixture of fat and water? ________________________________________________
__________________________________________________________________________________________
What is/are the end product(s) of fat digestion? _____________________________________________________________________
Is either of these end products acidic? If so, which one? ____________________________________________________________
Hypotheses/Predictions (See Methods section for details): :

- 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)?
