Worked Solution & Example Answer:The stages of an enzyme-controlled metabolic pathway are shown - Scottish Highers Biology - Question 12 - 2023
Step 1
C metabolite D binds with enzyme 1
Answer
In feedback inhibition, the product of a metabolic pathway (in this case, metabolite D) can inhibit the activity of an enzyme that acts earlier in the pathway (enzyme 1). This feedback mechanism helps to regulate the pathway and prevent the overproduction of the product when sufficient amounts are present. Therefore, option C is the correct answer.
