Cell Transport MidTerm Review

How do the structures of a cell membrane help control the transport of materials in and out of a cell? Please answer in a complete sentence.

In a complete sentence, explain two differences between active and passive transport. Please make sure to use key vocabulary terms such as: concentration gradient, ATP, equilibrium, homeostasis, high to low.

In complete sentences, please explain how cells change when placed in: hypotonic, hypertonic and isotonic solutions?

The diagram illustrates the activity of vesicles during a cellular process. Which statement best explains how vesicles are used during exocytosis?

• Delivering packaged materials to the Golgi apparatus for protein synthesis

• Exchanging genetic information between the Golgi apparatuses of separate cells

• Extracting portions of the Golgi apparatus to be regenerated for growth within the cell

• Transporting packaged molecules from the Golgi apparatus to be released out of the cell

Which statement describes the process of osmosis in an animal cell?

• Sugar molecules move across the plasma membrane until the cell has enough energy to grow in size and divide.

• Water molecules move across the plasma membrane until solute concentrations are equal on both sides of the membrane.

• Ions move across the plasma membrane until the inside of the cell has a higher concentration of positive charges.

• Enzymes move across the plasma membrane until the cell has completed metabolism.
