Step 1:Let's solve this step by step:
Step 2:: Understand the key terms
- Facilitated transport is a type of passive transport across cell membranes - Passive transport means molecules move without direct energy expenditure from the cell
Step 3:: Analyze the statement's components
- The statement claims that facilitated transport does not require cellular energy - It suggests that diffusion alone powers the molecular movement
Step 4:: Evaluate the mechanism of facilitated transport
- Facilitated transport uses protein channels or carrier proteins - Molecules move from high to low concentration - No direct ATP (cellular energy) is used in this process
Step 5:: Confirm the role of diffusion
- Diffusion is indeed the driving force in facilitated transport - Molecules move down their concentration gradient spontaneously - This movement does not require cellular energy input
Step 6:: Determine the statement's accuracy
- The statement is describing the fundamental principle of facilitated transport correctly - No cellular energy (ATP) is directly used in this process
Final Answer
Facilitated transport does not require the cell to use energy because moving molecules from areas of higher concentration to areas of lower concentration is powered by diffusion.
