Which cell would be best for studying lysosomes?

• Muscle cell

• Nerve cell

• Bacterial cell

• Phagocytic white blood cell

In what way do the membranes of a eukaryotic cell vary?

• Phospholipids are found only in certain membranes.

• Certain proteins are unique to each membrane.

• Only certain membranes of the cell are selectively permeable.

• Only certain membranes are constructed from amphipathic molecules.

According to the fluid mosaic model of membrane structure, proteins of the membrane are mostly

• spread in a continuous layer over the inner and outer surfaces of the membrane

• confined to the hydrophobic interior of the membrane

• embedded in a lipid bilayer

• randomly oriented in the membrane, with no fixed inside-outside polarity

Which of the following factors would tend to increase membrane fluidity?

• a greater proportion of unsaturated phospholipids

• a greater proportion of saturated phospholipids

• a lower temperature

• a relatively high protein content in the membrane

Which of the following processes includes all the others?

• Osmosis

• Diffusion of a solute across a membrane

• passive transport

• transport of an ion down its electrochemical gradient

Based on the figure, which of these experimental treatments would increase the rate of sucrose transport into a plant cell?

• decreasing extracellular sucrose concentration

• decreasing extracellular pH

• decreasing cytoplasmic pH

• adding a substance that makes the membrane more permeable to hydrogen ions
