Questions & Step-by-Step Solutions
Which of the following is an example of an allosteric inhibitor?
Step 1: Understand what an allosteric inhibitor is. An allosteric inhibitor is a molecule that binds to an enzyme at a site other than the active site, changing the enzyme's shape and reducing its activity.
Step 2: Identify the enzyme in the question. The enzyme mentioned is phosphofructokinase, which is important in the process of glycolysis (the breakdown of glucose for energy).
Step 3: Look for examples of molecules that can act as allosteric inhibitors. Citrate is one such molecule that can bind to phosphofructokinase.
Step 4: Confirm that citrate reduces the activity of phosphofructokinase when it binds, thus acting as an allosteric inhibitor.
Step 5: Conclude that citrate is indeed an example of an allosteric inhibitor.
