Cell Transport

Multiple Choice

Which of the following is NOT a form of passive transport?

• Simple Diffusion

• Facilitated diffusion

• Active transport

• Osmosis

Multiple Choice

How does facilitated diffusion differ from simple diffusion?

• Requires energy input

• Moves molecules from low to high concentration

• Occurs only in plant cells

• Involves transport proteins

Multiple Choice

What type of molecules can easily pass through the cell membrane by simple diffusion?

• Small nonpolar molecules

• Large polar molecules

• Ions

• Proteins

Multiple Choice

What happens to a cell placed in a hypertonic solution?

• It swells and bursts

• It shrinks due to water loss

• It remains the same size

• It absorbs solutes from the solution

Multiple Choice

Which of the following is true about osmosis in a hypotonic solution?

• Water moves out of the cell, causing it to shrink

• Water moves into the cell, causing it to swell

• Solutes move into the cell, causing it to shrink

• No net movement of water occurs

Multiple Choice

What is a key characteristic of active transport?

• It does not require energy

• It moves substances from high to low concentration

• It requires energy input from ATP

• It occurs only in plant cells

Multiple Choice

Which of the following is an example of active transport?

• Diffusion of oxygen into cells

• Osmosis of water across a membrane

• Facilitated diffusion of glucose

• Sodium-potassium pump

Multiple Choice

Which of the following best describes the role of carrier proteins in active transport?

• They facilitate the passive movement of molecules

• They form channels for water molecules

• They use ATP to pump substances across the membrane

• They enable the diffusion of small molecules

Multiple Choice

What is bulk transport?

• The active movement of large particles and macromolecules across a membrane

• The diffusion of gases across a membrane

• The passive movement of small molecules across a membrane

• The movement of water through osmosis

Multiple Choice

What type of bulk transport involves the cell taking in large particles by engulfing them?

• Exocytosis

• Phagocytosis

• Pinocytosis

• Facilitated Diffusion
