    2. BPlant cells have cell walls; plant cells do not
    3. CAnimal cells have mitochondria; plant cells do not
    4. DAnimal cells have centrioles; plant cells do not
    5. EAnimal cells have lysosomes; plant cells do not.
  2. 2Cells of the salivary gland and pancreas likely have a large amount of
    1. ADNA
    2. Bperoxisomes
    3. Crough endoplasmic reticulum
    4. Dsmooth endoplasmic reticulum
    5. Elysosomes
  3. 3All of the following are surrounded by a membrane EXCEPT
    1. ANucleus
    2. BBacteria
    3. CLysosome
    4. DChromosome
    5. EVacuole
  4. 4All of the following are true concerning mitochondria and chloroplasts EXCEPT
    1. AThey were once free-living prokaryotes
    2. BThey both perform mainly anabolic reactions
    3. CThey both have electron transport chains for ATP production
    4. DThey both perform chemiosmosis
    5. EThey both have DNA and ribosomes
  5. 5All of the following statements regarding cilia or flagella are true EXCEPT
    1. AThe flagella of prokaryotes and eukaryotes are analogous structures.
    2. BProkaryotes and eukaryotes have cilia.
    3. CThe cells lining the oviduct in mammals are ciliated.
    4. DThe cells lining the respiratory tract in humans are ciliated.
    5. ETHe sperm of ferns and mosses are flagellated.
  6. 6Pancreatic islet cells were cultured in a medium containing radio-labeled amino acids. Every five minutes, a sample of cells were removed from the culture, washed and fractionated. The radioactivity of each fraction was then measured. The results showed that in the first five minutes, most of the radioactivity was found in the rough ER. After 30 minutes, most of the radioactivity was found in the Golgi body. After 60 minutes, almost all of the radioactivity was found in the cell membrane. Which of the following is most likely the identity and function of the radio-labeled protein?
    1. AA hormone to lower blood glucose concentrations.
    2. BA hormone to raise blood glucose concentrations.
    3. CAn enzyme to oxidize glucose in the pancreas.
    4. DA receptor for a hormone that helps regulate blood glucose concentrations.
    5. EA neurotransmitter involved in appetite regulation.
  7. 7Which of the following shows the correct sequence of events regarding the radio-labeled protein in the cell from question 6?
    1. ANucleus --> cytoplasm --> ribosome --> rough ER --> Golgi --> exocytosis
    2. BNucleus --> rough ER --> Golgi --> membrane --> exocytosis
    3. CRough ER --> Golgi --> membrane
    4. DRough ER --> Golgi --> membrane --> exocytosis
    5. ERough ER --> Golgi --> lysosome --> membrane
  8. 8Which of the following best describes the mechanism of transport if a substance is observed to move down its concentration gradient (from high to low concentration) across a cell membrane at a much faster rate than expected by simple diffusion, but without the hydrolysis of ATP?
    1. AOsmosis
    2. BFacilitated diffusion
    3. CActive diffusion
    4. DActive transport
    5. ECyclosis
  9. 9Which of the following is a membrane-bound molecule responsible for active transport?
    1. AGlycolipid
    2. BProtein
    3. CPhospholipid
    4. DCholesterol
    5. EATP
  10. 10Red blood cells moved from an isotonic medium into distilled water would most likely
    1. Ashrivel.
    2. Bswell and lyse.
    3. Cnot change.
    4. Dbecome sickle shaped.
    5. Eundergo apoptosis.
