Grade 10 IGCSE Biology_Active Transport Quiz

What is active transport?

• Movement of molecules through diffusion

• Movement of molecules from high to low concentration

• Movement of molecules without energy

• Movement of molecules using energy from respiration

What type of proteins are required for active transport?

• Structural proteins

• Receptor proteins

• Carrier proteins

• Channel proteins

From which concentration does active transport move molecules?

• From equal concentration

• From low to high concentration

• From high to low concentration

• From outside to inside only

What energy source is used in active transport?

• Chemical energy from respiration

• Thermal energy

• Mechanical energy

• Light energy from photosynthesis

Which of the following is NOT a characteristic of active transport?

• Requires energy

• Occurs spontaneously

• Moves against the concentration gradient

• Involves carrier proteins

What is the main difference between passive and active transport?

• Active transport requires energy, passive does not

• Passive transport requires energy, active does not

• Both require energy

• Both move molecules in the same direction

What is the role of carrier proteins in active transport?

• To provide structural support

• To facilitate the movement of specific molecules

• To store energy

• To break down molecules

Which of the following statements is true about active transport?

• It only moves water

• It is a form of passive transport

• It occurs without energy

• It can move ions and molecules

Active transport is essential for which of the following?

• Maintaining cell structure

• Regulating temperature

• Producing energy

• Uptake of nutrients against concentration gradients

What happens to molecules during active transport?

• They move freely across the membrane

• They are stored in vacuoles

• They are broken down

• They are moved to areas of higher concentration
