Practical Biology

A collection of experiments that demonstrate biological concepts and processes.

Factors affecting enzyme activity

Enzymes are sophisticated catalysts for biological processes. These practicals (and the practicals at intermediate level) give you opportunities to explore how enzyme activity changes in different conditions.

Enzyme experiments often provide real ‘messy’ data, because their activity can change dramatically from one lesson to the next.

Experiments

Investigating the effect of pH on amylase activity
Microscale investigations of catalase activity in plant extracts
Investigating effect of temperature on the activity of lipase
Investigating an enzyme-controlled reaction: catalase and hydrogen peroxide concentration
Investigating effect of concentration on the activity of trypsin
