Cell Transport, Cell Cycle, and Cancer Quiz

Which of the following is an example of passive transport?

• Endocytosis

• Sodium-potassium pump

• Facilitated diffusion

• Exocytosis

What type of transport requires energy (ATP) to move substances across the membrane?

• Passive transport

• Simple diffusion

• Osmosis

• Active transport

During simple diffusion, molecules move:

• From low to high concentration

• Randomly without a concentration gradient

• From high to low concentration

• Against the concentration gradient using energy

In facilitated diffusion, molecules pass through the membrane with the help of:

• ATP

• Enzymes

• Protein channels

• Vesicles

Osmosis specifically refers to the movement of:

• Ions

• Water

• Glucose

• Proteins

A protein pump moves materials:

• From high to low concentration

• Against the concentration gradient

• Without using energy

• Through osmosis

Exocytosis is the process of:

• Taking in materials by engulfing them

• Using transport proteins to export large molecules

• Expelling materials from the cell via vesicles

• Breaking down organelles
