Cellular Respiration Quiz: Test

Do you think you understand well about cellular respiration? Cellular respiration occurs in both eukaryotic and prokaryotic cells, with most reactions taking place in prokaryotes' cytoplasm and the mitochondria of eukaryotes. Cellular respiration involves catabolic reactions in which large molecules are broken down into smaller molecules, and they release energy in the process. You can take a deep breath; this informative quiz will explain cellular respiration to you, and good luck with it.
