A 2-day-old newborn male is diagnosed with congenital lactic acidosis because of a defective electron transport protein. This de
ficiency leads to a decrease in the rate at which NADH and FADH2 can be oxidized to produce ATP using oxidative phosphorylation and results in an increase in cytosolic AMP. Under these conditions which glycolytic enzyme would be stimulated?
Phosphofructokinase-1 is the enzyme which is responsible in controlling glycolysis pathway when the ratio of ATP/AMP is altered.
<u>High levels of AMP and low levels of ATP in the body stimulates activity of the enzyme, Phosphofructokinase-1.</u> Thus, the process of glycolysis is stimulated when the energy charge falls.
