2.30: Understand that Bile is Produced by the Liver and Stored in the Gall Bladder, and Understand the Role of Bile in Neutralising Stomach Acid and Emulsifying Lipids

BILE: Bile is an Alkaline Substance Produced in the Liver and Stored in the Gall Bladder

FUNCTIONS OF BILE:

FUNCTIONS OF BILE

Diagram showing Where Bile is Produced

FUNCTIONS: EMULSIFYING LIPIDS Breaks down Lipids into Smaller Molecules with Larger Surface Area to Volume Ratio so Lipase can Break them Down Faster into Fatty Acids and Glycerol (This Process Usually takes a Long Time)     2. NEUTRALISING STOMACH ACID Enzymes in the Small Intestine work Best at the Optimum pH of 8-14 (Alkaline Conditions), But the Food that is Churned in the Stomach by Hydrochloric Acid is Acidic Bile Neutralises Hydrochloric Acid so allows an Alkaline Environment for Enzymes to work at their Optimum pH, Rate of Metabolic Reactions Increases
