Diffusion and Active Transport Quiz

What is the name for the passive process when molecules can move through the phospholipids of the plasma membrane?

• Passive Diffusion

• Facilitated Diffusion

• Active Transport

• Bulk Transport

How do channel proteins work?

• Channel Proteins allow ions, small molecules, and water to pass through their channel in either direction

• Channel Proteins move everything through the membrane

• Channel proteins allow molecules to move out of the membrane

• Channel Proteins block the membrane to molecules

What is the name for the process when energy (ATP) is required to move molecules through the membrane?

• Passive Diffusion

• Facilitated Diffusion

• Active Transport

• Bulk Transport

What is the correct statement about active transport?

• It requires the use of carrier proteins

• It requires the fusion of vesicles with the plasma membrane

• It does not requires the release of ATP energy

• It requires the movement of channel proteins to outside the cell

Which of these is an example of bulk transport?

• Active transport

• To move large molecules out of the cell

• Endocytosis

• Endocytosis and exocytosis

What happens to the surface area of the cell during exocytosis?

• It decreases

• It remains the same

• It increases

• It depends on the type of molecule being transported

What is the importance of active transport in the body?

• To bring in essential molecules even when there are already a lot in the cell

• To remove unwanted molecules from the cell

• To maintain the balance of ions and polar molecules in the body

• To regulate the movement of small molecules across the plasma membrane
