Worked Solution & Example Answer:Fungi were cultured in a fermenter to produce an enzyme that was released into the culture medium - Scottish Highers Biology - Question 18 - 2019
Step 1
The concentration of enzyme when the dry mass of fungus was 36 units per litre
Answer
To determine the concentration of enzyme when the dry mass of fungus reaches 36 units per litre, we need to analyze the graph provided.
- Locate 36 units per litre on the dry mass scale, which is the vertical axis on the left side of the graph.
- Draw a horizontal line from the 36-unit mark to intersect the enzyme concentration curve.
- Follow this intersection point vertically down to see where it meets the enzyme concentration axis (the right vertical axis).
Upon examining the graph, we see that the enzyme concentration corresponding to a dry mass of 36 units per litre is approximately 28 units per litre. Hence, the correct answer is
B 28 units per litre.
