Cellular Respiration {Ans: The process of how cells get energy.}Glycolysis {Ans: Glucose is partially broken down in the cytoplasm. Produces ATP but also uses it to run. From 1 glucose, 2 ATP, 2 Pyruvate, 2 NADH were produced.}Krebs Cycle {Ans: The second step in cellular respiration. Chemical reactions occur in the mitochondria. Uses the products of glycolysis and produces several NADH electron molecules and carbon dioxide.}NADH {Ans: NAD+ once it has picked up an electron/ and electron transporter.}Methanogenesis {Ans: The biological production of methane gas. Uses carbon dioxide and hydrogen to make water, methane, and ATP.}Pyruvate {Ans: Broken down food molecule produced during glycolysis in the cytoplasm.}FADH2 {Ans: FAD once it has picked up an electron/ a electron transporter.}Electrons and ATP {Ans: Electrons pass through electron transport chains which fuel hydrogen pumps. The pumps pump hydrogen ions from one side of the membrane to the other. The hydrogen ions return to the other side by going through the ATP Synthase which uses protons to combine ADP and phosphate into ATP.}Anaerobic processes {Ans: Processes without oxygen.}Aerobic Processes {Ans: Processes with oxygen.}NAD+ {Ans: An electron carrier used in cellular respiration.}Glucose
