Cell Transport 1

The movement of molecules across a membrane from high concentration to low concentration is called:

• Osmosis
• Diffusion
• Endocytosis
• Active Transport

Active Transport typically uses ______ to transport materials across the cell membrane.

• ATP
• Glucose
• Na+
• K+

When the concentration of particles inside of a cell is the same as the concentration of particles outside of the cell. 

• active transport
• concentration
• diffusion
• equilibrium

The process where only water is allowed to pass through the cell membrane from a high to low concentration.

• meiosis
• respiration
• diffusion
• osmosis

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

• Active transport
• Passive transport
• Diffusion
• Osmosis

Cells transport material across a cell membrane without using energy (high to low concentration)

• Passive transport
• Concentration
• Endocytosis
• Active Transport

In passive transport, substances move across the cell membrane ________ the concentration gradient

• AGAINST

• ALONG

• DOWN

• BETWEEN
