Exam 6: A Tour of the Cell

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

Cytochalasin D is a drug that prevents actin polymerization. A cell treated with cytochalasin D will still be able to carry out which of the following processes?

Both the volume and the surface area for three different cells were measured. These values are listed in the following table: Using data from the table above, select the best explanation for why that cell will be able to eliminate waste most efficiently?

Which organelle is the primary site of ATP synthesis in eukaryotic cells?

Amoebae move by crawling over a surface (cell crawling), which involves ________.

In bacteria, DNA will be found in ________.

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

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.

Which structure is common to plant and animal cells?

One primary advantage of light microscopy over electron microscopy is that ________.

Cyanide binds with at least one molecule involved in producing ATP. If a cell is exposed to cyanide, most of the bound cyanide is likely to be localized within the ________.

Which domains of life are classified as prokaryotes?

Cilia and flagella bend because of ________.

Which structure is common to plant and animal cells?

A defect in which of the following intercellular junctions would allow partially digested material to leak passively between the cells of the small intestine into the abdominal cavity?

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

The liver is involved in detoxification of many poisons and drugs. Which of the following structures is primarily involved in this process and, therefore, abundant in liver cells?

Which structure is not part of the endomembrane system?

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?

In the fractionation of homogenized cells using differential centrifugation, which of the following will require the greatest speed to form pellets at the bottom of the tube?
