B.11 Osmosis and Transport 4choice

Movement of molecules from an area of high concentration to areas of low concentration

• equilibrium
• concentration gradient
• diffusion
• osmosis

The difference in the concentration of molecules across a distance

• diffusion
• osmosis
• equilibrium
• concentration gradient

The concentration of molecules will be the same throughout the space the molecules occupy

• equilibrium
• diffusion
• effusion
• osmosis

The process of water molecules moving across a cell membrane from an area of high concentration to an area of low concentration.

• osmosis
• diffusion
• facilitated diffusion
• simple diffusion

concentration of solute molecules outside the space is lower than the concentration of solute molecules inside the space

• osmosis
• hypotonic
• isotonic
• hypertonic

concentration of solute molecules inside the space is lower than concentration of solute particles outside the space

• hypotonic
• hypertonic
• isotoic
• equilibirum

Passive transport used for molecules that cannot readily diffuse through the cell membrane

• diffusion
• facilitated diffusion
• simple diffusion
• osmosis

proteins in the membrane specifically used in facilitated diffusion

• carrier proteins
• ion channels
• facilitated diffusion
• cell membrane

membrane bound proteins that transfer ions

• facilitated diffusion
• simple diffusion
• active transport
• ion channels

concentration of solute is equal inside and outside of the cell

• hypertonic

• isotonic

• hypotonic

• osmosis
