Cell transport

Cell transport

Multiple Choice

Which illustration of transport across the membrane requires energy?

• A
• B
• C
• D

Multiple Choice

Which form of transport is being shown in the diagram.

• diffusion
• osmosis
• facilitated diffusion
• active transport

Multiple Choice

Cells use energy to move materials across a membrane (low to high concentration).

• Active transport
• Passive transport
• Diffusion
• Osmosis

Active Transport

 relies on the use of energy to move substances into and out of cells. Usually, molecules are traveling against a concentration gradient.

Multiple Choice

If the sodium concentration inside a cell is greater than outside the cell, how can a cell take in more sodium?

• osmosis
• diffusion
• active transport
• passive transport

Protein pumps

Multiple Choice

When a cell forms a vesicle around unwanted particles and expels it OUT of the cell.

• Pinocytosis

• Endocytosis

• Receptor-mediated

• Exocytosis

Multiple Choice

Particles are removed from a cell (pushed out).

• Endocytosis
• Exocytosis
• Permeable
• In high concentration

Multiple Choice

Which type of active transport uses a vesicle to allow a large molecule to exit the cell?

• Endocytosis

• Exocytosis

Exocytosis a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.

Multiple Choice

A type of active transport that brings particles into a cell when the cell membrane encloses a particle to make a vesicle

• Diffusion
• Passive Transport
• Active Transport
• Endocytosis

Multiple Choice

In this image, the cell is using which type of molecular transport?

• Osmosis
• Diffusion 
• Endocytosis
• Exocytosis 

Endocytosis

 the process by which cells take in substances from outside of the cell by engulfing them in a vesicle.

Multiple Choice

Compare the concentrations of the sugar in the cell and the solution.  Which is HYPOTONIC?

• Cell
• Solution

Multiple Choice

Facilitated diffusion is the movement of materials into and out of the cell

• with the use of energy
• with the use of proteins but no energy
• by moving water
• by using ATP

Multiple Choice

The  movement of water from a high concentration to a low concentration is called

• diffusion
• osmosis
• facilitated diffusion
• active transport

Multiple Choice

In this situation, where the solute is illustrated by red dots, predict if will WATER move into or out of the cell, and how that will affect the cell.

• Water will move into the cell and the cell will expand.
• Water will move into the cell and the cell will shrink.
• Water will move out of the cell and the cell will expand.
• Water will move out of the cell and the cell will shrink.

Multiple Choice

Semi-permeable mean to allow

• all materials across the membrane
• only some materials across the membrane
• no material to cross the membrane
• to allow only water across the membrane

Multiple Choice

Which type of active transport is displayed?

• Endocytosis

• Exocytosis
