Which statements best describe the difference between active transport and passive transport?
Understand the Problem
The question is asking about the differences between active transport and passive transport in biological systems. It specifically seeks to identify the correct statements that describe each process, indicating their requirements and mechanisms.
Answer
B
The final answer is B: Active transport requires ATP. Passive transport does not require ATP.
Answer for screen readers
The final answer is B: Active transport requires ATP. Passive transport does not require ATP.
More Information
Active transport requires energy, typically in the form of ATP, to move substances against their concentration gradients, while passive transport does not require energy and relies on concentration gradients.
Tips
A common mistake is to confuse the direction of molecule movement with the energy requirement. Remember, active transport requires energy input, whereas passive transport does not.
