A. 33% B, 40% D. 80%. E. 99% 98. The pathway for the synthesis of a plasma membrane (PM) localized receptor is: (Note, not all steps are indicated) A. ER bound ribosome Golgi PM B. Free ribosome mitochondrion Golgi PM C. Free ribosome Smooth ER Golgi PM D, ER bound ribosome Golgi lysosome PM E. ER bound ribosome Golgi Peroxisome PM 99. Movement of vesicles within the cell depends on what cellular structures? A. actin filaments and motor proteins icrotubules and motor proteins C. actin filaments and ribosomes D. centrioles and motor proteins E. actin filaments and microtubules 100. Which of the following statements regarding enzymes is TRUE? A. Enzymes increase the rate of a reaction by reducing the rate of reverse reactions. B. Enzymes increase the rate of a reaction by making the reaction more exergonic. C. Enzymes increase the rate of a reaction by lowering the activation energy barrier. D. Enzymes change the equilibrium point of the reactions they catalyze, E. Enzymes make the rate of a reaction independent of substrate concentrations. 101. In which structures would you NOT expect to find RNA? B. Nucleus C. Vacuole D. Ribosom 102. (1 pt) Which organelle or structure is absent in plant cells? B. gap junctions D. Golgi vesicles 103. Which one of the statoments, A-D, if any, is true? A. The purine base thymine is found in DNA but not in RNA. B. DNA is only found in the nucleus in a eukaryotic cell. C, RNA is only found in the cytosol in a eukaryotic cell. D. Both DNA and RNA contain the same pyrimidine and purine bases. E. None of the above statements are correct. 104. The phosphate transport system in bacteria imports phosphate into the cell even when the concentration of phosphate outside the cell is much lower than the cytoplasmic phosphate concentration.
