Down: 1) Is a partial degradation of sugars that occurs without O2. ; Process of regenerating NAD+ with either an inorganic or organic compound serving as the final electron acceptor; occurs in the absence of oxygen.2) Three-carbon keto acid that can be decarboxylated and oxidized to make acetyl CoA, which enters the Citric Acid Cycle under aerobic conditions; the end product of glycolysis.3) Chemical reactions that transfer electrons between reactants.; Chemical reaction that consists of the coupling of an oxidation reaction and a reduction reaction.5) Is the stored energy created when a cell pumps postively charged hydrogen ions (protons) across a membrane.7) Completes the breakdown of glucose.; (also Krebs Cycle) Series of enzyme-catalyzed chemical reactions of central importance in all living cells for extraction of energy from carbohydrates.8) Addition of a high-energy phosphate to a compound, usually a metabolic intermediate, a protein, or ADP.11) Process in which there is a production of adenosine triphosphate (ATP) in cellular metabolism by the involvement of a proton gradient across a membrane.12) Soluble electron transporter in the electron transport chain (ETC) that connects the 1st or 2nd complex to the 3rd. 13) Alternate name for the citric acid cycle, named after the group name for citric acid, tricarboxylic acid (TCA)14) Removal of a phosphate group from a molecule15) Breaks down glucose into two molecules of pyruvate.; Process of breaking glucose into two three-carbon molecules with the production of ATP and NADH.18) Is a biological process in which microorganisms like yeast convert sugars into ethanol (alcohol) and carbon dioxide. Because it occurs in the absence of oxygen, it is an anaerobic process.20) Is the electron acceptor22) Is the electron donor26) A substance loses electrons, or is oxidized.27) A substance gains electrons, or is reduced (the amount of positive charge is reduced). Across: 4) Alternate name for the Citric Acid Cycle, named after Hans Krebs, who first identified the steps in the pathway in the 1930s in pigeon flight muscles; see Citric Acid Cycle.6) Electrons are passed through a number of proteins including these (Each with an iron atom) to O2 (OXYGEN).9) Integral membrane protein that transports glucose. 10) Molecule bound to a protein that facilitates the function of the protein. 16) Membrane-embedded protein complex that adds a phosphate to ADP with energy from protons diffusing through it.17) Includes both aerobic and anaerobic respiration but is often used to refer to aerobic respiration. 19) Are microorganisms (like certain bacteria) that can only survive and grow in environments completely lacking oxygen.21) Combination of an acetyl group derived from pyruvic acid and coenzyme A, which is made from pantothenic acid (a B-group vitamin)23) Consumes organic molecules and O2 and yields ATP. Process in which organisms convert energy in the presence of oxygen. 24) Process that does not use oxygen. 25) Production of ATP from ADP using the excess energy from a chemical reaction and a phosphate group from a reactant.28) Is an organism that can survive and grow in both the presence and absence of oxygen.29) Enzyme that converts a molecule into its isomer30) Process in which organisms convert energy for their use in the absence of oxygen.31) Is an anaerobic process (without oxygen) where bacteria, yeast, or muscle cells convert sugars into energy, producing lactic acid as a byproduct.
