A. Mitochondrion A. CO2; ATP; Hydrogen ions (protons) Q. Explain the role of ADP in relation to the small amount of energy released during the first stage of Q. For what is ATP an abbreviation? respiration. A. First stage uses energy, combines with phosphate, to form ATP. ATP stores energy in high energy bond Q. What is the first stage process of respiration called? A. Adenosine Triphosphate Q. The electrons released in Kreb's Cycle pass along a transport chain and release energy. To what use is this energy put? A. To form ATP A. Glycolysis Q. What is the final product of the first stage of respiration under aerobic conditions? Q. To what are the electrons transferred at the end of the electron transport chain in aerobic respiration? A. Pyruvic acid (Pyruvate) A. Oxygen; H+ (protons) Q. If conditions in a human muscle cell become anaerobic pyruvic acid is converted to another substance. Name this other substance. Q. Where in the cell does the first stage of respiration occur? A. Cytoplasm A. Lactic acid Q. In Stage 2 of respiration Q. To what is pyruvic acid (pyruvate) electrons pass along an electron converted under anaerobic transport chain, releasing energy. In conditions in yeast? what molecule is this energy stored? Page 1 of 4 A. Ethanol & CO2 A. ATP Q. Under aerobic conditions pyruvate is converted to an acetyl group and a small molecule is released. Name this small molecule. Q. Name the group of protein molecules that control the rate of respiration. A. Carbon dioxide A. Enzymes Q. In the first stage of respiration there is a release of ATP as glucose is converted to another substance. Name this other substance. A. Pyruvic acid (pyruvate) Q. In aerobic respiration the acetyl group enters a cycle of reactions. What name is given to this cycle? Q. What is fermentation? A. Anaerobic respiration; Respiration that produces lactic acid or ethanol & CO2 Q. Is oxygen required for the first stage of respiration? A. Krebs cycle A. No Q. Name a compound to which pyruvate (pyruvic acid) may be converted, in the absence of oxygen. Q. C6H12O6 + 6O2 ENERGY + 6CO2 + 6H2O Is this the equation for photosynthesis or respiration? A. Lactic acid; Ethanol & CO2 A. Respiration Q. In what part of the cell does the second stage of respiration take place? Page 2 of 4 Q. How did you know that fermentation had ceased? A. Mitochondrion A. Bubbling stopped Q. In the mitochondrion pyruvate is broken down to CO2 and a twoQ. Is oxygen required for the second carbon compound. Name this twostage of respiration? carbon compound. A. Acetyl Co-enzyme A A. Yes Q. Give one product, other than electrons, of the reactions in Kreb’s cycle. Q. Where does Kreb’s cycle take place?
