The enzyme invertase breaks down sucrose into its two component monosaccharides.
Describe how you would keep the variable you have named in (a)(iv) at a constant value.
A description that makes reference to the following points:
- dissolve a stated mass of \{invertase / sucrose\} in a stated volume of water / use a stock solution of \{sucrose / invertase (1)
- use the same volume of this solution for each pH (1)
