Match the definition given with the correct vocabulary term.
__ The process that most cells use to release energy, requires oxygen and carbon based food molecules. A. Krebs Cycle ( Citric Acid Cycle)
__ The third step in cellular respiration. Occurs in the mitochondria where a series of proteins use high-energy electrons to convert ADP into ATP. B. ATP
__ Adenosine Triphosphate, a special molecule that can store energy for cells to use later. C. ATP Synthase
__ The second stage of cellular respiration. This is an aerobic step that occurs in the mitochondria in which pyruvic acid is broken down into carbon dioxide which is released. D. Metabolic Rate
__ Acts like a tiny motor that needs energy from the mitochondria to spin and thus create ATP. E. Glycolysis
__ The first step of cellular respiration. This is an anaerobic step that occurs in the cytoplasm where glucose is broken down into a more useable form called pyruvate. F. Electron Transport Chain
__ Form of cellular respiration carried out by some prokaryotes that live in environments with no oxygen. G. Aerobic Cellular Respiration
__ The total amount of energy used by an animal in a unit of time. H. Anaerobic Cellular Respiration
