bioNRICH is the area of the stemNRICH site devoted to the

designed to help develop the mathematics required to get the most
from your study of biology at A-level and university.
A spectophotometric assay is made by mixing a salt solution, acid buffer, bacterial cells and an enzyme catalyst. Using your skills of proportional reasoning, work out the volumes of given reagents required to create the standard assay. There are two different types of question: one in which you find the missing volumes and another in which you find the missing concentrations. Type your
answers into the boxes and check them or generate new questions using the buttons.
