IGCSE Biology Exam - Paper 6 Revision Notes BIO Enzyme activity lab: 2H2O2 (l) → 2H2O (l) + O2 (g) This reaction can be catalysed by an enzyme (catalase) or by a non- biological catalyst (Manganese IV oxide) 1. Put 3cm2 of hydrogen peroxide in a test tube. 2. Add fresh potato strips and shake gently. 3. Keep your thumb on top of the test tube, or use a stopper, to retain the gas. 4. Do the “glowing splint” test → the splint relights Positive control: repeat the original experime...
