Transportation Quiz

What is active transport?

• The movement of molecules across a cell membrane without the use of energy from ATP.

• The movement of molecules across a cell membrane with their concentration gradient, requiring the use of energy from ATP.

• The movement of molecules across a cell membrane against their concentration gradient, requiring the use of energy from ATP.

• The movement of molecules across a cell membrane with their concentration gradient, without the use of energy from ATP.

Give an example of active transport.

• Sodium-potassium pump

• Simple diffusion

• Facilitated diffusion

• Osmosis

What is passive transport?

• Process of molecules moving across a cell membrane with the use of energy.

• Process of molecules moving against the concentration gradient.

• Process of molecules moving across a cell membrane without the use of energy

• Process of molecules moving through protein channels.

Give an example of passive transport.

• Osmosis

• Active transport

• Endocytosis

• Diffusion

What is diffusion?

• The movement of molecules or particles from an area of high concentration to an area of low concentration.

• The movement of molecules or particles from an area of low concentration to an area of high concentration.

• The movement of molecules or particles from an area of high concentration to an area of equal concentration.

• The movement of molecules or particles from an area of low concentration to an area of equal concentration.

How does diffusion occur?

• Particles move from an area of high concentration to an area of low concentration.

• Diffusion occurs through active transport.

• Particles move randomly in all directions.

• Particles move from an area of low concentration to an area of high concentration.

What is osmosis?

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

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

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

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

What is the main difference between osmosis and diffusion?

• Osmosis refers to the movement of solute molecules, while diffusion refers to the movement of solvent molecules.

• Osmosis specifically refers to the movement of solvent molecules across a semipermeable membrane, while diffusion refers to the movement of any type of molecule from an area of higher concentration to an area of lower concentration.

• Osmosis occurs only in living organisms, while diffusion occurs in both living and non-living systems.

• Osmosis requires energy input, while diffusion is a passive process.

What are the types of passive transport?

• Hypertonic, Hypotonic, Isotonic

• Filtration, Pinocytosis, Phagocytosis

• Diffusion, Osmosis, Facilitated diffusion

• Active transport, Endocytosis, Exocytosis

Explain the process of active transport.

• Active transport is the movement of molecules across a cell membrane against their concentration gradient, requiring the use of energy.

• Active transport is the movement of molecules across a cell membrane with their concentration gradient, requiring the use of energy.

• Active transport is the movement of molecules across a cell membrane without the use of energy.

• Active transport is the movement of molecules across a cell membrane in the same direction as their concentration gradient, requiring the use of energy.
