Enzymes And Food Test Flashcards
What are digestive enzymes used for?
They are used to break down large food molecules into smaller food molecules that are easily able to be absorbed through the small intestine walk into the bloodstream.
What do protease enzymes include?
They include pepsin (stomach enzyme, and trypsin (small intestine)
What do carbohydrase enzymes include?
Amylase (saliva in the mouth)
Maltase, surcease and lactase.
Found in the small intestine.
Substrate of amylase?
Starch.
Source of pepsin?
Stomach
Substrate of pepsin?
Proteins
Product of pepsin
Peptides
Source of trypsin
Pancreas
Where are lipase enzymes found?
Small intestine.
What is a protein molecule made up of?
Many different amino acids.
What does protease break down?
Protein molecules.
Protein molecules transfer to…?
Amino acids
A starch molecule is made up of many…?
Glucose molecules
What does carbohydrase break down?
Carbohydrate molecules
Carbohydrase turns into…?
Glucose
A fat molecule is made up of…? And…?
Fatty acid and glycerol molecules
What does lipase break down?
Fat molecules.
The lock and key model.
What is it?
The lock is the enzyme, and the key is the substrate. Only the correctly sized key (substrate) fits into the key hole (active site) of the lock (enzyme).
What are enzymes?
Protein molecules.
Enzymes are… That speed up…
They are biological catalysts that speed up reactions in cells.
What is the optimum temperature of most enzymes?
37 degrees.
What happens if an enzyme is too hot?
The shape of the enzyme is changed. The enzyme had been denatured. The substrate can no longer fit into the active site.
What gives the maximum rate of reaction?
The optimum PH or temperature is that which gives the maximum rate of reaction.
