Bell Work 10/26 - Cell Transport

Which illustration of transport across the membrane requires energy?

• A
• B
• C
• D

Which form of transport is being shown in the diagram.

• diffusion
• osmosis
• facilitated diffusion
• active transport

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

• Active transport
• Passive transport
• Diffusion
• Osmosis

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

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

• Pinocytosis

• Endocytosis

• Receptor-mediated

• Exocytosis

Particles are removed from a cell (pushed out).

• Endocytosis
• Exocytosis
• Permeable
• In high concentration

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

• Endocytosis

• Exocytosis

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

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

• Osmosis
• Diffusion 
• Endocytosis
• Exocytosis
