Flashcard: Digestive System: Enzymes and Absorption — 9 carte

Hydrochloric acid — role?

Creates low pH to denature microbes and prime pepsin.

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

Mouth, salivary glands, oesophagus, stomach, small/large intestines, pancreas, liver, gallbladder

Function of bile

Neutralises acid, emulsifies fats for digestion

Fat emulsification process

Breaks large fat droplets into smaller ones

Small intestine regions

Duodenum for digestion, ileum for absorption
