Cyanide binds to at least one molecule involved in producing ATP. In a cell exposed to cyanide, most of the cyanide will be in ________.

Which of the following parameters is most likely to limit the maximum size of a cell?

The nuclear lamina is an array of intermediate filaments that line the inner surface of the nuclear membrane. Disassembly of the lamina by chemical treatment would most likely result in which of the following consequences?

Peroxisomes in liver cells detoxify alcohol by removing hydrogen atoms and combining them with which of the following molecules?

Which of the following statements describes a major advantage of light microscopy over electron microscopy?

Ions can travel directly from the cytoplasm of one animal cell to the cytoplasm of an adjacent cell through which of the following structures?

Which of the following molecules is required by cells to assemble cilia or flagella?

Gaucher disease is the most common genetic disorder affecting lipid storage in humans. The disease is caused by deficiency of an enzyme necessary for the breakdown of lipids, which leads to the accumulation of fatty material in organs of the body including the spleen, liver, kidneys, lungs, brain, and bone marrow. Which of the following statements provides the most plausible explanation for how organelles are impacted by Gaucher disease.

Which of the following structures is common to plant and animal cells?

Which of the following statements best describes the function of the nuclear pore complex found in eukaryotic cells?
