10
New cards

proteins: broken down into?

broken down into amino acids

11
New cards

how do enzymes help digestion?

they break down large molecules that we eat into smaller, soluble molecules which can be absorbed through the intestinal lining

12
New cards

how is starch broken down?

they are broken down by amylase into smaller sugars - called maltose/glucose

13
New cards

how are proteins broken down?

they are broken down by protease into amino acids

14
New cards

how are lipids broken down?

they are broken down by lipases into both glycerol and fatty acids

15

  • small intestine

  • salivary glands (mouth)

16
