Passive

Passive Transport

• Does require cell energy

• Does NOT require cell energy

Osmosis is a form of ______________. 

• Passive Transport

• Active Transport

Which of the following moves with the concentration gradient?

• Active Transport

• Phagocytosis

• Pinocytosis

• Diffusion 

Which statement best describes passive transport?

• The movement of molecules from a high to low concentration without energy

• The movement of molecules from low to high concentration without energy

• The movement of water against the concentration gradient

• Passive transport requires ATP energy to go against the gradient

Which claim is supported by this osmosis image?

• There is an equal amount of water movement inside and outside the cell

• Water is moving out of the cell because the solute concentration is higher outside than inside

• Solutes are moving into the cell to balance it inside and outside

• None of these correctly describe the image

Passive transport moves from a _______ concentration to a ________ concentration.

• high to low

• high to high

• low to high

• low to low

Which statement is best supported?

• diffusion of molecules from a high to low concentration

• a protein channel moves molecules from high to low concentration

• Water is being moved across the membrane from low to high

• Na (sodium) is being selectively tansported
