Salmon
B
Vegetable oil
C

Slide 4 - Quiz

What tips could you give someone who wants to have a healthy diet?

Slide 5 - Question ouverte

ingestion-digestion-absorption-elimination

Slide 6 - Diapositive

digestion
mechanical => chewing
chemical  => breaking food down using enzymes

Slide 7 - Diapositive

enzymes 
substrate is broken down

Slide 8 - Diapositive

Slide 9 - Diapositive

Chemical digeston step 1: 
  • the place: the mouth (oesophagus)
  • the enzyme: amylase
  • the liquid: saliva
  • the nutrient: carbohydrates
  • the products: glucose & maltose

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

Slide 10 - Diapositive

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.

Slide 11 - Diapositive

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.

Slide 12 - Diapositive

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
