Enzymes And Protiens Flashcards
What does pepsin turn protein into?
Peptides
What does the enzyme amylase do?
Starch_______amylase______>maltose
What enzyme turns fats into fatty acids and glycerol?
Lipase
What does catalase do?
Hydrogen peroxide—catalase–>
=water and oxygen
What enzyme turns glucose into starch?
Potato phosphorylase
Give 2 examples of degradation enzymes
Amylase
Pepsin
Catalase
Lipase
Five an example of a synthesis enzyme?
Potato phosphorylase
What are enzymes used in?
Detergents
Cheese making
Genetic engineering
What is meant by the term denatured?
The active site of the enzyme has changed shape and the substrate can no longer fit into it
What are enzymes affected by?
Temperature and pH
What does optimum mean?
The condition at which something works best
What does biological detergent contain?
Enzymes
What is an advantage of biological detergent?
Removes stains better
Washes at low temperatures
If starch is present it turns iodine solution from..
Orange/brown. To blue/black
Where is pepsin found in the body?
In the stomach
Where are enzymes found?
In the cytoplasm of every living cell
What is an enzyme?
It is a biological catalyst that speeds up the rate of reaction without being used up
What are enzymes made from?
Protein
What is meant by-
Enzymes are specific
They work on only one substrate
How are enzymes specific
Because of the shape of their active sites
What expression is used to describe the way the substrate fits with the active site?
Like lock and key
