The Eukaryotic cell has a nucleus
Because the heat of the ocean mixed with the cold air above the ocean causes a hurricane
Eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH
