LESSON 7

KERBOODLE PAGE 54

Chemical digeston step 1: 

• the place: the mouth (esophagus)
• the enzyme: amylase
• the liquid: saliva
• the nutrient: carbodrates
• the products: glucose & maltose

• The enzymes in your saliva start breaking down the carbohydrate molecules into maltose and glucose.

Chemical digeston step 2: 

• the place: the stomach
• the enzyme: protease
• the liquid: chyme and hydrochloric acid
• the nutrient: proteins
• the products: amino acids

• The enzymes in your chyme start breaking down the protein molecules into amino acids.

Extra info about the stomach: 

• the place: the stomach
• the enzyme: rennin
• the liquid: chyme
• the nutrient: milk
• the products:turns the proteins in milk solid and lump together so it is easier to digest

Before chemical digeston step 3: 

• the place: liver
• the enzyme: none
• the liquid: bile
• the nutrient: fats

• Bile is an alkalyne and neutralises the acid in the chyme. (drops the pH).
• Bile emulsifies (breaks chemical bonds) fats.

Chemical digeston step 3: part A

• the place: the duodenum
• the enzyme: lipase
• the liquid: chyme and bile
• the nutrient: fats
• the products: fatty acids and glycerol

Chemical digeston step 3: part B

• the place: the duodenum
• the enzyme: amylase
• the liquid: chyme 
• the nutrient:carbohydrates and maltose
• the products: glucose

Chemical digeston step 3: part C

• the place: the duodenum
• the enzyme: protease
• the liquid: chyme 
• the nutrient:proteins
• the products: amino acids
