• Passive Transport

• Facilitated Diffusion

• Active Transport

• Osmosis

Water can move across a cell membrane using this type of passive transport.

• Dissolving

• Osmosis

• Sodium-Potassium Pump

• Facilitated Diffusion

Which of the following structures facilitates the process of active transport, using energy to move materials against the concentration gradient.

________ transport is when energy is used to move substances against the concentration gradient.

When substances move with the ​ (a)   , Materials move from ​ (b)   to ​ (c)   .

• concentration gradient
• higher concentration
• lower concentration

In ​ (a)   , materials move with the concentration gradient without assistance. In ​ (b)   , materials also move with the concentration gradient but they need the assistance of a carrier protein.

• simple diffusion
• facilitated diffusion

The process of how things move in and out of the cell through the cell membrane is ............
