The committed step of glycolysis is phosphofructokinase, which is inhabited by: a) high concentration of fructose 6-phosphate b) high concentration of ADP c) high concentration of ATP d) high concentration of fructose 1,6-bisphosphate 02. In eukaryotic organisms, fermemtation occurs: a) in the presence of oxygen b) in the absence of oxygen c) at all times d) in the presence of CO2 03. How many carbon atoms are in the molecues that participate in the energy- yielding (eergy pay-off) reactions in the process of glycolysis a) six carbons b) four carbons c) three carbons d) two carbons 04. Why not just stop at pyruvate in the absence of oxygen? Why lactate? a) The reaction from pyruvate to lactate converts NADH back to NAD, which is required for glycolysis. b) The reaction from pyruvate to lactate converts ADP to ATP. c) The reaction from pyruvate to lactate converts ATP to ADP. d) The reaction from pyruvate to lactate generates energy. 05. Of the following processes, which feeds the elctron transport chain? a) just the Kerbs cycle b) glycosis c) All NADH generating processes including glycolysis, the Kerbs cycle, and the conversion of pyruvate to acetly CoA d) fermentation 06. What is the final electron acceptor in the electron transport chain? a) NADH b) carbon dioxide c) acetyl CoA d) oxygen 07. In prokaryotes, the components of the electron transport chain are located in the: a) Inner membrane of mitochondria b) outer membrane of mitochondria c) in the cell membrane d) in the matrix of mitochondria 08. Which of the following is the correct path of electrons during the light reactions? a) photosystem II: electron transport chain: photosystem I b) photosystem I: electron transport chain: photosystem II c) electron transport chain: photosystem I: photpsystem II d) photosystem II: photosystemI: electron transport chain 09. Which electron transport chain produce NADPH in the chloroplast? a) the electron transport chain after the last photosystem b) the electron transport chain between the two photosystems c) the electron transport chain priduces ATP 10. When photosystem I absorbs a photon, electrons are ejected from the reaction center. What is the final destination of these electrons? a) The electrons are used to replace other electrons lost from photosystem II b) Electrons end up being captured by the elctron carrier NADPH c) They are accepted directly by ATP d) They were last seen at the tables in Vegas 11.
