Cell Transport

The Cell Membrane (Check all that apply):

• Transports raw materials into the cell

• Transports materials out of the cell

• Encloses the cell giving it shape

• Is made of phospholipids and proteins

Factors that can affect Diffusion (check all that apply):

• Distance

• Concentration

• Temperature

• Wavelength

The difference in concentration across a cell membrane is called:

• The Difference

• A concentration gradient

• Dynamic equilibrium

• Equilibrium

Water moves:

• From low solute concentration to high solute concentration

• From high solute concentration to low solute concentration

• From left to right

• From isotonic to leadertonic

When water concentration inside the cell equals water concentration outside the cell:

• Isotonic Conditions

• Hypotonic Conditions

• Hypertonic Conditions

• Leadertonic Conditions

When water concentration outside the cell is greater than water concentration inside the cell:

• Isotonic Conditions

• Hypotonic Conditions

• Hypertonic Conditions

• Leadertonic Conditions

When water concentration inside the cell is greater than water concentration outside the cell:

• Isotonic Conditions

• Hypotonic Conditions

• Hypertonic Conditions

• Leadertonic Conditions

Facilitated diffusion happens when (check all that apply):

• Some molecules are too large to pass through the membrane

• Some molecules have a charge

• Molecules move against the concentration gradient

• People swear

Transport proteins are made up of (check all that apply):

• Carrier Proteins

• Carbohydrates

• Phospholipids

• Channel Proteins

• Cholesterol

Active Transport occurs (check all that apply):

• Against a concentration gradient

• With no energy added

• With energy added

• In the intestinal cells

• Down a concentration Gradient
