The digestive systems of young mammals are not fully developed.
Enzymes such as amylase, maltase and protease are often added to baby food to aid chemical digestion.
The optimum temperature for the enzymes in the baby food to work was found to be 37°C.Â
Fig. 1 below shows a graph of the activity of an enzyme as temperature increases.Â

Add the following labels to the graph:
- Optimum temperature
- Denatured enzymeÂ
The label on the jar of baby food states that food must be thrown away if heated above 37°C.Â
Explain the need for this label.Â
