Cell Transport Quizlet

How do the particles move in diffusion?

• Facilitated diffusion

• High to low concentration

• Energy

• Active transport

What does the cell membrane look like?

• Composed of peptidoglycan

• Surrounded by a membrane

• Composed of phospholipids

• Proteins and lipids

How does water move in osmosis?

• Only through active transport mechanisms

• Area of high to low concentration

• In a random manner without any concentration gradient

• Cell membrane

What is the movement of small particles across a selectively permeable membrane like the cell membrane until equilibrium is reached?

• Diffusion

• Osmosis

• Passive Transport

• Endocytosis

What happens to a cell in an isotonic solution?

• Swells or sometimes even bursts

• Active - ATP is energy

• Shrinks or shrivels

• Stays the same

What happens to a cell in a hypotonic solution?

• Undergoes rapid division and replication

• Remains unchanged in size and shape

• Swells or sometimes even bursts

• Shrinks and becomes dehydrated

What kind of transport requires molecules to move with the concentration gradient?

• Isotonic

• Osmosis

• Passive transport

• Diffusion

What are the proteins that assist in facilitated diffusion; move substances down their concentration gradient?

• Endocytosis

• Carrier proteins

• Diffusion

• Ion channel

What is also known as cell drinking?

• Pinocytosis

• Phagocytosis

• Osmosis

• Exocytosis

What two macromolecules make up the cell membrane?

• Glucose and oxygen

• Nucleic acids

• Carbohydrates and lipids

• Proteins and lipids
