Hydrochloric acid role

Creates low pH, denatures microbes, primes pepsin

Enzymes — function?

Speed up reactions without being consumed.

Pepsin activity dependence

Depends on optimal stomach pH

Enzymes vs mechanical digestion

Enzymes break molecules; physical breakdown is mechanical

Digestive organs list

Function of bile

Neutralises acid, emulsifies fats for digestion
