How quickly does cellular respiration take place? Which of the following molecules plays the most important role in regulating the rate that the glycolysis proceeds? a. Acetyl-CoA b. Pyruvate c. Oxygen availability d. Phosphofructokinase (PFK) e. availability of FAD ...
ATP: Adenosine Triphosphate (ATP) is the energy that drives all living things. ATP comprises adenosine diphosphate (ADP) and a phosphate group, which are then split into ADP and inorganic phosphate (Pi). The ATP cycle is the series of biochemical reactions in cells to produce, store, and co...
Explain how phosphofructokinase (PFK) can both use ATP and be inhibited by it. Describe the function of ATP synthase and bc1 complex. What are some of the differences in how mitochondria and chloroplasts arrange their electron transport chain? Explain the difference between glycolysis an...
As an allosteric enzyme, PFK does not follow Michalis–Menton kinetics and therefore, Km values do not apply. Instead, S0.5 values are used. The in vitro and in situ S0.5 values of PFK are 0.2 and 0.4 mM [29]. The S0.5 value for F6P is 22 μM, which is near the intracellular ...
