CELL TRANSPORT

Students are observing particles moving against the concentration gradient in a lab investigation. Which type of transport are they observing?

• osmosis

• active Transport

• facilitated diffusion

• diffusion

This picture is a representation of what type of transport?

• Osmosis because it is diffusing through a protein from an area of high concentration to low concentration.

• Facilitated diffusion because it is diffusing through a protein from an area of high concentration to low concentration.

• Facilitated diffusion because it is diffusing through a protein from an area of low concentration to high concentration.

• Simple diffusion because it is diffusing through a protein from an area of high concentration to low concentration.

Which of these is not a form of passive transport?

• Endocytosis

• Diffusion

• Osmosis

• Facilitated Diffusion

What type of active transport does food move into the cell?

• Endocytosis

• Exocytosis

• Sodium Potassium Pump

• Diffusion

What is the definition of OSMOSIS?

• Diffusion of water through a selectively permeable membrane

• Molecular structure that surrounds the cell and controls what enters and leaves the cell

• Movement of molecules across the cell membrane against the concentration gradient

• Movement of molecules across the cell membrane from an area of high concentration to low concentration

Why would the cell need energy to move molecules across the membrane?

• the molecule is going against the concentration gradient

• the molecule is to large to pass through the membrane

• the lipid membrane requires energy anytime something is moving across the membrane

What is the definition of FACILITATED DIFFUSION?

• Movement of molecules across the cell membrane from an area of high concentration to low concentration

• Diffusion of water through a selectively permeable membrane

• Movement of molecules across the cell membrane against the concentration gradient

• Molecular structure that surrounds the cell and controls what enters and leaves the cell

The cellular process in which materials are moved across a membrane from an area of low concentration to an area of high concentration is called:

• Diffusion

• Osmosis

• Active Transport
