Cell Membranes and Transport Review

Which part of the cell membrane did the peanut butter and jelly represent in our lab?

• The middle region

• The hydrophobic part

• The part that does not like water

• All of these

Hydrophobic means

• Water Loving

• Water Hating

• Water Saturated

• Some Water

Hydrophillic means......

• Water Loving

• Water Hating

• Water Saturated

• Some Water

In our lab yesterday the bread represented

• The hydrophobic part of the cell membrane

• The hydrophillic part of the cell membrane

• The hairy part of the cell membrane

• The small part of the cell membrane

The macromolecules that make up the cell membrane are called

• plasma membrane

• membrane proteins

• cell wall

• osmosis

This is molecular movement across a cell membrane that DOES requre use of energy (ATP)

• Passive Transport

• Osmosis

• Active Transport

• All of these

This is molecular movement across a cell membrane that DOES NOT require energy (ATP)

• Passive Transport

• Osmosis

• Active Transport

• None of These

Simple Diffusion........

• Is the movement of molecules from high to low concentration

• Can happen across a cell membrane

• Will create balance in a concentration

• All of these

A membrane protein can help move molecules from high to low concentration. This is.......

• Passive Transport

• Active Transport

• Osmosis

• Facilitated Diffusion

This is the movement of water molecules across a semi-permeable membrane. *Our egg lab showed how this happens.......

• Active Transport

• Passive Transport

• Osmosis

• Facilitated Diffusion
