✨ Perfect 5 marker ✨

1. The active site of the enzyme is complementary to the lipase molecule
2. so they fit together like a lock and key
3. the enzyme can bind to the substrate
4. and the substrate is broken down into products
5. the products are released and the enzyme remains unchanged

Amylase/protease/lipase

Digestive enzymes convert food into small soluble molecules that can be absorbed into the bloodstream.

• Amylase breaks down starch into sugar/glucose
• Protease breaks down proteins to amino acids.
• Lipase breaks down lipids/fats to glycerol and fatty acids. </aside>

Bile and its uses

Bile is made in the liver and stored in the gall bladder.

1. Emulsification of fats: Breaks the fat down into smaller droplets. The larger surface area allows lipase enzymes to digest the fat quicker
2. Alkaline so neutralises stomach acid: PH of the small intestine is optimal for the lipase enzymes to digest fats. (they aren't denatured)
