Enzymes catalyze all chemical reactions in cells. The reaction rate of an enzyme can change depending on the temperature, pH level, ionic concentration and other factors. A cell can also control the...
By nature if you have healthy cells they will automatically split on their own. The rates of splitting does not vary. The only time someones splitting would be lesser or greater than a normal person...
Many factors can influence the rates of reaction Enzymes or Catalysts can reduce the activation energy for a reaction, speeding it up hundreds or thousands of times the "normal rate" Temperature The...
