Description

Specifications

Enzymes are affected by pH in two ways
In the first instance, electrostatic charges on groups at the enzymes active sites are modified, and, secondly those charges are responsible for holding the molecular shape and active configuration may be disrupted
Both of the above factors have significant influence on the catalytic properties of the enzymes
These effects are illustrated using the enzyme Amylase and Invertase
Suitable for A‐level or tertiary level students
Experiments included:Effect of pH on Invertase activity
Effect of extremes of pH on stability of invertase
