Enzymes and Bubbles (VCE SSCE Biology): Flashcards

Breaks down hydrogen peroxide

Water (H₂O) and oxygen gas (O₂)

Damages cells and important molecules

$2\text{H}_2\text{O}_2 \rightarrow 2\text{H}_2\text{O} + \text{O}_2$

Active catalase present; oxygen released

Type of sample tested

Whether bubbles were produced

Living materials (not heat-treated/dead ones)

Denatures (destroys) them

35°C and pH 8.2
