Understanding Active and Passive Transport

Which of the following best describes the process of diffusion in passive transport?

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

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

• Movement of water molecules through a semi-permeable membrane

• Movement of molecules using energy from ATP

What is the main difference between active transport and passive transport?

• Active transport requires energy, while passive transport does not

• Passive transport requires energy, while active transport does not

• Both require energy but in different forms

• Both do not require energy

Which of the following is an example of active transport?

• Osmosis

• Facilitated diffusion

• Sodium-potassium pump

• Simple diffusion

In which direction do molecules move during passive transport?

• Against the concentration gradient

• Along the concentration gradient

• Randomly, without any specific direction

• Towards the area with the highest energy

Which of the following statements is true about facilitated diffusion?

• It requires energy in the form of ATP

• It involves the use of transport proteins

• It moves molecules against their concentration gradient

• It is a type of active transport

What role do carrier proteins play in active transport?

• They provide energy for the transport process

• They help move substances across the cell membrane against the concentration gradient

• They allow substances to move freely across the cell membrane

• They act as a barrier to prevent substances from entering the cell

Match the following forms of active transport.

• Exocytosis

• moving large materials into the cell from low to high

• Endocytosis

• moving large materials out the cell from low to high

• Sodium/Potassium Pump

• moving ions
