Answer:
The principle benefit of regulating glycolysis by the concentration of ATP is to signals the cell to stop glycolysis as sufficient amount of ATP is already present in the biological system.
Explanation:
Phosphofructokinase 1  is allosterically inhibited by ATP.Glycolysis is a catabolic as well as exergonic process which deals with the oxidation of glucose to form pyruvate along with ATP molecules.
             When ATP is present at high concentration within our body at that time there is no need to synthesize additional ATP because ATP is already present in sufficient amount.
        To maintain its own homeostasis ATP allosterically inhibit the catalytic activity of phosphofructokinase. As a result glycolysis is inhibited and the glucose molecule can be utilized in other metabolic pathways.
 
        
             
        
        
        
Genetic drift happens by chance and can make an allele disappear completely from a gene pool, even if it was a desirable trait that should have been passed down to offspring. The random sampling style of genetic drift shrinks the gene pool and therefore alters the frequency the alleles are found in the population.
