Worked Solution & Example Answer:At the end of 10 minutes, the amount of glucose produced in test tube two when compared to test tube one would be A - VCE - SSCE Biology - Question 7 - 2009 - Paper 1
Step 1
C. lower as there would be fewer collisions between the substrate and the enzyme.
Answer
At 15°C, the enzymatic activity would be significantly reduced compared to the optimal temperature of 37°C. Enzymes have an optimal temperature at which they function most effectively. At lower temperatures, the kinetic energy of molecules is reduced, leading to fewer collisions between the enzyme and the substrate. Consequently, the production of glucose from lactose via the enzyme is expected to decrease in test tube two compared to test tube one.
