Worked Solution & Example Answer:The graph shows the substrate and product concentrations during a reaction in a metabolic pathway - Scottish Highers Biology - Question 8 - 2022
Step 1
At which time is the product concentration exactly 50% of the substrate concentration?
Answer
To find the time when the product concentration is exactly 50% of the substrate concentration, we can observe the graph provided. The substrate concentration is close to 100 mg/l when the product concentration reaches 50 mg/l. By examining the graph, it can be seen that this occurs at approximately 60 seconds.
Therefore, the correct answer is B: 60 seconds.
