You have two enzymes, 1 and 2. Both convert substance A into substance B. 1 is inhibited by B, because B partially blocks the active site and will not allow more A to enter. 2 is inhibited by a third substance, C, which binds to the back of 2 and changes its shape so that A cannot bind to the active site.
a. What type of inhibitor is B?
b. What type of inhibitor is C?
c. What is one advantage of using the regulatory strategy of enzyme 1 compared to enzyme 2?
d. What is one advantage of using the regulatory strategy of enzyme 2 compared to enzyme 1?
