Required practical - Investigating enzymes (AQA GCSE Biology Combined Science): Flashcards

Simple sugars

$\frac{1}{\text{time}}$

pH where rate is highest/enzyme works best

Mixtures that resist pH changes/keep pH steady

Ensures rate changes only due to pH changes

When iodine no longer changes colour

Low rate/works slowly

Every 30 seconds

25°C

Vertical: rate of reaction; Horizontal: pH
