- The presence of cholesterol in the plasma membranes of some animals
- When biological membranes are frozen and then fractured, they tend to break along the middle of the bilayer. The best explanation for this is that
- Which of the following types of molecules are the major structural components of the cell membrane?
- Singer and Nicolson's fluid mosaic model of the membrane proposed that
- Some regions of the plasma membrane, called lipid rafts, have a higher concentration of cholesterol molecules. As a result, these lipid rafts
- Who was/were the first to propose that cell membranes are phospholipid bilayers?
- Which cell would be best for studying lyosomes?
- What is the most likely pathway taken by a newly synthesized protein that will be secreted by a cell?
- Cyanide binds with at least one molecule involved in producing ATP. If a cell is exposed to cyanide, most of the cyanide will be found within the
- Which structure-function pair is mismatched?
- Which of the following is present in a prokaryotic cell?
- Which structure is common to plant and animal cells?
- Which structure is not part of the endomembrane system?
- A biologist ground up some plant leaf cells and then centrifuged the mixture to fractionate the organelles. Organelles in one of the heavier fractions could produce ATP in the light, whereas organelles in the lighter fraction could produce ATP in the dark. The heavier and lighter fractions are most likely to contain, respectively,
- A newspaper ad for a local toy store indicates that a very inexpensive microscope available for a small child is able to magnify specimens nearly as much as the much more costly microscope available in your college lab. What is the primary reason for the price difference?
- A biologist wants specifically to examine the surfaces of different types of cells in kidney tubules of small mammals. The cells in question can be distinguished by external shape, size, and 3-D characteristics. Which of the following would be the optimum method for her study?
- What types of proteins are not synthesized in the rough ER?
- ECM proteins are made by ribosomes in which part of a eukaryotic cell?
- Recent evidence shows that signals from the extracellular matrix (ECM) can regulate the expression of genes in the cell nucleus. A likely mechanism is that
- Which of the following makes it necessary for animal cells, although they have no cell walls, to have intercellular junctions?
- Ions can travel directly from the cytoplasm of one animal cell to the cytoplasm of an adjacent cell through
- Plasmodesmata in plant cells are most similar in function to which of the following structures in animal cells?
- The extracellular matrix is thought to participate in the regulation of animal cell behavior by communicating information from the outside to the inside of the cell via which of the following?
- A mutation that disrupts the ability of an animal cell to add polysaccharide modifications to proteins would most likely cause defects in its
