Unit 2 EOC Review

Against the concentration gradient, from low concentration to high concentration, uses ATP; this decribes.....

• facilitated diffusion
• osmosis
• active transport
• simple diffusion

In which direction will these molecules diffuse?

• from right to left
• from left to right
• they will not move at all
• they will move in both directions equally

Special protein channels help move particles from high concentration % to low concentration %, but NO energy is needed. Moves objects like glucose. This is..

• facilitated diffusion
• exocytosis
• active transport
• equilibrium

What is the movement of water molecules from an area of high concentration to low concentration? Hint: Specifically Water

• Mitosis

• Osmosis

• Passive Transport

• Active Transport

Which form of active transport is being shown?

• Pinocytosis
• Endocytosis
• Exocytosis
• Osmosis

The sodium-potassium pump usually pumps

• only potassium ions and sugar molecules
• potassium ions out of the cell
• sodium ions into the cell
•  potassium ions into the cell

Which form of active transport is being shown?

• Facilitated Diffusion
• Exocytosis
• Endocytosis
• Protein Pumps

What type of transport is this?

• Endocytosis
• Facilitated Diffusion
• Active Transport Pump
• Osmosis

Why does the sodium potassium pump require energy?

• It's moving molecules against their concentration gradients
• It's moving molecules with their concentration gradient
• It doesn't

What is the function of ATP in living things?

• provides energy for cells
• stores genetic information
• provides structure in the nucleus
