question		réponse
What happens in the mouth? commencer à apprendre		Food is chewed and mixed with saliva. Amylase begins starch digestion.
What does amylase do? commencer à apprendre		Amylase breaks down starch into sugars.
What is the peristalsis? commencer à apprendre		Wave-like muscle contractions that move food through the digestive system.

What is bile? commencer à apprendre		An alkaline substance that neutralises stomach acid and emulsifies fats.
What does emulsify mean? commencer à apprendre		Breaking large fat droplets into smaller droplets to increase surface area.
Why is bile important? commencer à apprendre		It creates alkaline conditions for lipase and increases the rate of fat digestion.
What does the lipase do? commencer à apprendre		Lipase breaks lipids into fatty acids and glycerol.
