Exam 6: A Tour of the Cell

Which of the following will have the greatest ratio of surface area to volume?

Which of the following would be most appropriate method to observe and measure the size of ribosomes in a eukaryotic cell?

Which structure is common to plant and animal cells?

The nuclear lamina is an array of intermediate filaments that line the inner side of the nuclear membrane. If a chemical treatment caused the lamina to disassemble, what would you expect to be the most likely immediate consequence?

Which of the following structures form cytoplasmic channels that connect adjacent plant cells through the cell walls?

Which structure is common to plant and animal cells?

Cells require which of the following to form cilia or flagella?

Which of the following organelles produces and modifies polysaccharides that will be secreted?

Ions can travel directly from the cytoplasm of one animal cell to the cytoplasm of an adjacent cell through ________.

Where are proteins produced other than on ribosomes free in the cytosol or ribosomes attached to the endoplasmic reticulum?

Spherocytosis is a human blood disorder associated with a defective cytoskeletal protein in the red blood cells (RBCs). What do you suspect is the consequence of such a defect?

Researchers investigating the mechanism of vesicular transport assembled a cell-free system that included microtubule tracks, vesicles, and ATP. However, they observed no movement of transport of vesicles in this system. What were they missing?

Cilia and flagella bend because of ________.

Cyanide binds to at least one molecule involved in producing ATP. If a cell is exposed to cyanide, most of the cyanide will be found within the

A characteristic 9 + 2 arrangement of microtubules, consisting of nine doublets of microtubules surrounding a pair of single microtubules is associated with ________.

Which of the following is the most common pathway taken by a newly synthesized protein that will be secreted by a cell?

Which domains of life are classified as prokaryotes?

Suppose a young boy is always tired and fatigued, suffering from a metabolic disease. Which of the following organelles is most likely malfunctioning in this disease?

Tay-Sachs disease is a human genetic abnormality that results in cells accumulating and becoming clogged with very large, complex, undigested lipids. Which cellular organelle is most likely defective in this condition?

Gaucher disease is the most common of lipid storage diseases in humans. It is caused by a deficiency of an enzyme necessary for the breakdown of lipids. This leads to the accumulation of fatty material in organs of the body including the spleen, liver, kidneys, lungs, brain, and bone marrow. Using your knowledge of the structure of eukaryotic cells, identify the statement below that best explains how internal membranes and the organelles of cells may be involved in Gaucher disease.
