Homework Answers
Answer - Option 1 will be CORRECT.
ATP inhibits the phosphofructokinase reaction by raising the K m for fructose‐6‐phosphate. AMP activates the reaction. Thus, when energy is required (Means when ATPs are low), glycolysis is activated. When energy is plentiful, the reaction is slowed down.

Adenosine monophosphate (AMP) is a regulatory molecule in metabolic processes such as glycolysis and gluconeogenesis. For example, it stimulates the glycolytic enzyme phosphofructokinase, and therefore ATP production, and it inhibits the gluconeogenic enzyme fructose 1,6-bisphosphatase. Adenylate kinase catalyzes the reversible reaction shown here: 2 ADP =(Mg2+)= ATP + AMP During periods of intense activity, when glycolysis is used in the generation of ATP, the reaction lies to the right, decreasing [ADP], generating ATP, and accumulating AMP. However, [ATP] is usually...

If a cell does not have mitochondria, it cannot harvest the entire energy stored in a molecule of glucose? A)True B)False Phosphofructokinase is an enzyme that is important for the breakdown of the glucose molecule to generate ATP. In regards to that, when the ATP levels are high, the phosphofructokinase is inhibited. What do you expect to happen to the enzyme when the levels of ATP within the cell drop? 1.The enzyme will be activated. 2.The enzyme will be deactivated....
