Cell Transport Quick Check

When small non polar molecules cross the phospholipid bilayer from an area of high concentration to an area of low concentration.

• Active transport

• Osmosis

• Simple Diffusion

• Facilitated diffusion

When polar molecules, ions, or larger molecules move across the plasma membrane through a channel protein from a higher concentration to a lower concentration.

• Facilitated diffusion
• Endocytosis
• Active transport
• Osmosis

The movement of wateracross the plasma membrane from an area of higher concentration to an area of lower concentration

• Diffusion
• Osmosis
• Active transport
• Filtration

The movement of molecules from an area of low concentration to high concentration which requires the use of energy (ATP).

• Facilitated diffusion
• Osmosis
• Passive transport
• Active transport

If the outside of the cell has 20% Carbon Dioxide and the inside of the cell has 80% Carbon dioxide, which direction will the molecules move?

• The molecules will move outside the cell.
• The molecules will move in both directions.
• The molecules will remain stationary.
• The molecules will move inside the cell.

Potassium (K+) moves across the plasma membrane via facilitated diffusion. There is 20% K+ on the outside of the cell and 80% K+ on the inside of the cell. Which direction will the K+ ions move?

• K+ ions will move in both directions equally.
• K+ ions will remain inside the cell.
• K+ ions will move outside the cell.
• K+ ions will move into the cell.

The Sodium Potassium uses active transport to push ions against their concentration gradients. If a cell has 70% Sodium on the outside and 30% on the inside of the cell. Which direction will the Sodium Ions move?

• Sodium will leave the cell

• Sodium will move into the cell

• Sodium doesnt move
