Cell Membrane Function and Processes Quiz

What is the primary function of the cell membrane?

• To store genetic information

• To produce energy for the cell

• To serve as a boundary and regulate entry and exit of substances

• To act as an impenetrable wall

Which of the following molecules can pass readily through the cell membrane?

• Ions

• Oxygen

• Glucose

• Proteins

What is the process called when the cell membrane actively pumps molecules or ions?

• Facilitated transport

• Diffusion

• Passive transport

• Active transport

Which structure is used by cells to transport extremely large molecules across the membrane?

• GluT transporters

• Vacuoles

• Protein pumps

• Ion channels

What is the process called when cells release large molecules by merging vacuoles with the cell membrane? (Think of when we release YOU from McCall!)

• Endocytosis

• Osmosis

• Exocytosis

• Phagocytosis

Which process allows white blood cells to consume other cells?

• Exocytosis

• Facilitated transport

• Phagocytosis

• Active transport

What is the similarity between endocytosis and exocytosis?

• Both involve the release of substances from the cell

• Both involve the intake of substances into the cell

• Both involve the formation of vacuoles

• Both involve the use of ion channels
