#5. the mitochondria
#8. photosynthesis removes co2 from the air and celluar resperiation puts it back
#9. they are similar because they both begin with glycolysis which breaks down the glucose molecules and they both produce atp. They are different because water molecules are not produced during fermentation and all of fermentations cycles are in the cytoplasm while only the first cycle in celluar resperiation occurs in cytoplasm
