Protease
What is the enzyme used to break down fat?
Lipase
What happens at optimum temperature?
The enzyme becomes denatured and loses its shape
What happens as temperature increases?
Particles vibrate more and have more kinetic energy, leading to more collisions and a faster reaction
Bile emulsifies…
Fats
Emulsification
Breaking something down into smaller pieces
How does emulsifying fats help digestion?
Tiny droplets have higher SA for lipases to work
Where are fatty acids and glycerol absorbed?
In the small intestine using villi
