Question
Which enzyme is amylase?
Markscheme
A
Examiners report
Question 20 was criticised because students are only expected to know one source of amylase and this could be the salivary glands, but it if they knew that the substrate of amylase is starch and the product is maltose the only possible answer was the correct one.
