Membrane Transport

When substances move from an area of high concentration to an area of low concentration, this is:

• Endocytosis

• Diffusion

• Phagocytosis

• Active Transport

The head of a phospholipid is attracted to water, and is referred to as:

• Hydroscopic

• Hydrogenated

• hydrophobic

• Hydrophilic

 What process occurs when WATER diffuses across a membrane?

• Simple Diffusion

• Active Transport

• Osmosis

• Facilitated diffusion

The following diagram shows:

• Active Transport

• Osmosis

• Diffusion

• Exocytosis

Which type of transport requires an input of energy?

• Active Transport

• Osmosis

• Facilitated diffusion

• Simple diffusion

non-polar molecules cannot move across the membrane unless there is a channel

• True

• False

Carbohydrates or sugars needs carrier proteins to cross the plasma membrane

• True

• False

Secondary active transport is when a substance move from high concentration to low concentration to provide energy for another molecule to move from low to high concentration

• True

• False

Symporter is when ions move in opposite directions

• True

• False

When contents are released outside the cell through vesicles, this is:

• Endocytosis

• Mitosis

• Exocytosis

• Osmosis
