how does atp made from pyruvate?
 ATP is created through a complex enzyme-driven process. There are a couple of ways this works in cells: -glycolysis, in which glucose is broken up into two subunits, called pyruvate, which creates two units of ATP per molecule of glucose. This happens in the cytoplasm, in both animal and plant cells. -respiration, in which pyruvate is combined with oxygen to form carbon dioxide and water, which creates a lot of ATP per unit of pyruvate.
