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: is produced in the liver and stored in the gall bladder

Enzymes work best in alkaline conditions: food is acidic from being in the stomach. Bile is alkaline so when it is released into the small intestine it allows the enzymes to work (neutralizes stomach acid) Bile also emulsifies fat: give it a larger surface are which means it easier for lipases to work
