question 121

Multiple Choice

Phosphofructokinase is an allosteric enzyme in the pathway that breaks down glucose to produce ATP. Regulation of glycolysis is directly related to the level of ATP and citrate. If ATP or citrate levels are high, phosphofructokinase is inhibited. What will happen to this enzyme when ATP levels drop?

• A)Phosphofructokinase is inhibited.
• B)Phosphofructokinase is activated.
• C)Metabolism of citrate is inhibited.
• D)Metabolism of phospholipids is activated.
• E)Metabolism of phospholipids is inhibited.
