Biology 2.1.6 Flashcards
What is the Purpose of ‘Digestion’?
The Purpose of Digestion is to Break Down Large, Insoluble Molecules into Smaller, Soluble Molecules that can be Absorbed into the Bloodstream.
What are the 3 main types of Digestive Enzyme? What do they Digest? (3)
-Carbohydrases: Carbohydrates.
-Proteases: Proteins.
-Lipases: Fats.
Carbohydrases Break Down ___ to ___ ___.
Carbohydrates, Simple Sugars.
Common Example of Carbohydrase Enzyme:
Amylase.
Where is Amylase Produced in the Body? (3)
-Salivary Glands.
-Pancreas.
-Small Intestine.
Proteases Break Down ___ into ___ ___.
Proteins, Amino Acids.
Where are Proteases Produced? (3)
-Stomach.
-Pancreas.
-Small Intestine.
Lipases Break Down ___ to ___ & ___ ___.
Fats, Glycerol, Fatty Acids.
Where are Lipase Enzymes Produced in the Human Body? (2)
-Produced in the Pancreas.
-Secreted into the Duodenum.
Cells in the Liver Produce ___, which is used an a Neutralising Agent.
Bile.
Bile is Stored in the…
Gallbladder.
Bile has 2 main roles: (2)
-Alkaline, so Neutralises the Acidic Substances from the Stomach before they enter the Alkaline Intestines.
-Breaks Down Large Molecules of Fat into Smaller ones, Increasing Surface Area. This is known as Emulsification.
What is ‘Emulsification’?
When the Bile Breaks Down Large Molecules of Fat into Smaller ones, which Increases Surface Area.
