Chapter 7 Cellular Respiration

Terms : Hide Images
35107457Cellular Respirationthe process by which cells obtain energy from carbohydrates; atmospheric oxygen combines with glucose to form water and carbon dioxide
35107458Glycolysisthe anaerobic breakdown of glucose to pyruvic acid, which makes a small amount of energy available to cells in the form of ATP
35107459Pyruvic Acidthe three-carbon compound that is produced during glycolysis and needed for both the aerobic and anaerobic pathways of cellular repiration that follow glycolysis
35107460NADHthe reduced form of NAD+; an electron-carrying molecule that functions in cellular respiration
35107461Anaerobicdescribes a process that does not require oxygen
35107462Aerobic Respirationthe process in which pyruvic acid is broken down and NADH is used to make a large amount of ATP; the part of respiration that is carried out in the presence of oxygen
35107463NAD+ (nicotinamide adenine dinucleotide)an organic molecule that serves as an electron carrier by being oxidized to ___ and reduced to NADH
35107464Fermentationthe breakdown of carbohydrates by enzymes, bacteria, yeasts, or mold in the absence of oxygen
35107465Lactic Acid Fermentationthe chemical breakdown of carbohydrates that is called ______ as the main end product
35107466Alcoholic Fermentationthe anaerobic process by which yeasts and other microorganisms break down sugars to form carbon dioxide and ethanol
35107467Kilocaloriesa unit of energy equal to 1,000 calories
35107468Mitochondrial Matrixthe fluid that is inside the inner membrane of a mitochondrion
35107469Acetyl CoA (acetyl coenzyme A)a copmound that is synthesized by cells and that plays a major role in metabolism
35107470Krebs Cyclea series of biochemical reactions that convert pyruvic acid into carbon dioxide and water; it is the major pathway of oxidation in animal, bacterial, and plant cells, and it releases energy
35107471Oxaloacetic Acida four-carbon compound of Krebs cycle that combines with Acetyl CoA to form citric acid
35107472Citric Acida six-carbon compound formed in the Krebs cycle
35107473FAD (flavin adenine dinucleotide)a compound that acts as a hydrogen acceptor in dehydrogenation reactions
