BIOLOGY: Cell Membrane Transport Review

What does CONCENTRATION refer to with particles?

• Amount of particles in a given space.

• Color of particles
• Size of particles
• Mass of particles in a given space.

What does it mean if an area has a HIGHER CONCENTRATION of particles?

• Fewer particles present
• No particles present
• More particles present
• Particles are evenly distributed

What does it mean if an area has a LOWER CONCENTRATION of particles?

• Fewer particles
• Greater density
• Higher concentration
• More particles

What does EQUILIBRIUM mean?

• State of motion or movement
• State of balance or things being equal.

• State of chaos or confusion
• State of imbalance or instability

What is PASSIVE TRANSPORT?

• Passive transport is the movement of substances across a cell membrane without the use of energy.
• Passive transport is the movement of substances across a cell membrane through active transport.
• Passive transport is the movement of substances from a lower concentration to a higher concentration.
• Passive transport is the movement of substances across a cell membrane using energy.

What are 2 types of PASSIVE TRANSPORT?

• Diffusion and Active Transport

• Active Transport and Exocytosis

• Osmosis and Active Transport

• Diffusion and Osmosis

What happens during DIFFUSION?

• Particles move from an area of lower concentration to an area of higher concentration.
• Particles move randomly in all directions.
• Diffusion only occurs in liquids and gases.
• Particles move from an area of higher concentration to an area of lower concentration.

Does DIFFUSION require the use of energy?

• Yes
• Sometimes
• Only in certain conditions
• No

What happens during OSMOSIS?

• Movement of water molecules from an area of higher water concentration to an area of lower water concentration.

• Movement of water molecules from an area of lower water concentration to an area of higher water concentration without a semipermeable membrane.

• Movement of water molecules from an area of lower solvent concentration to an area of higher solvent concentration through a semipermeable membrane.

• Movement of solvent molecules from an area of higher solute concentration to an area of lower solute concentration through a semipermeable membrane.

Does OSMOSIS require the use of energy?

• No
• Sometimes
• Only in certain conditions
• Yes
