The enzyme phosphofructokinase-1 (PFK-1) catalyzes the 3rd reaction in glycolysis. When AMP concentrations are very high, AMP binds to PFK-1, activating it. Of what is this an example? What are enzymes? What is the molecule that is the result of an enzyme-catalyzed reaction?
Metabolic reprogramming, which was first observed in tumor cells by Otto Warburg, is characterized by an increase in glucose metabolism, also known as glycolysis. This phenomenon, termed the Warburg effect, persists even in the presence of oxygen and is characterized by increased glucose uptake and ...
All of the different types of biomolecules can serve as energy sources. Explain which biomolecules are catabolized in which metabolic pathways. Phosphofructokinase (PFK-1) is one of the most regulated enzymes in metabolism. Which of the following would be expected to be an allosteric activ...
In the third reaction of glycolysis, F-6-P is converted tofructose-1,6-bisphosphate(F-1,6-BP). In this phosphorylation step, the phosphate again comes from ATP, but this time it is added to a different carbon atom. The enzyme responsible isphosphofructokinase(PFK). •In many phosphorylat...
