Types of Transport

Other particles consumed by deer mice, such as calcium, have to move into the cells by active transport. Which diagram correctly shows the movement of particles into the cells by active transport?

When glucose is broken down, carbon dioxide is produced, which results in more carbon dioxide inside the cell than outside the cell. The carbon dioxide then diffuses out of the cell.

Which statement best describes the movement of carbon dioxide by diffusion?

• The carbon dioxide can move through the plasma membrane by moving down the concentration gradient.

• Water molecules are needed to move the carbon dioxide across the plasma membrane.

• Peripheral proteins help move the carbon dioxide across the plasma membrane.

• The transport of carbon dioxide through the plasma membrane require energy from ATP.

Select the 3 types of passive transport

• Endocytosis

• Simple Diffusion

• Exocytosis

• Osmosis

• Facilitated diffusion

This type of transport does not require energy and moves down the concentration gradient from a high concentration to a low concentration.

• Active transport

• Passive transport

This type of transport requires energy (ATP) and moves against the concentration gradient moving from a low concentration to a high concentration.

• Active transport

• Passive transport

This type of transport moves from high concentration to low concentration and passes directly through the membrane.

• Facilitated diffusion

• Simple diffusion

• Endocystosis

• Active transport

This is the transfer of water across a membrane from an area of high concentration to an area of low concentration.

• Simple diffusion

• Facilitated diffusion

• Osmosis

• Active transport

What type of tonicity is this? What way does the water move?

• Hypotonic, the water moves into the cell causing the cell to swell

• Isotonic, there is no net movement the cell stays the same

• Hypertonic, the water moves out of the cell causing the cell to shrink

The black dots represent the solute (salt or sugar). What is the tonicity of this solution? Which way will the water move?

• Hypotonic, the water will move into the cell causing the cell to swell

• Isotonic, there is no net movement of water the cell will stay the same

• Hypertonic, the water will move out of the cell causing the cell to shrink
