Verified step by step guidance

Step 1: Understand the concept of membrane transport processes. Membrane transport processes are mechanisms by which substances move across the cell membrane. These processes can be passive (not requiring energy) or active (requiring energy in the form of ATP).

Step 2: Review the characteristics of each transport process mentioned in the problem: Facilitated diffusion, Simple diffusion, Osmosis, and Active transport. Passive processes like facilitated diffusion, simple diffusion, and osmosis do not require ATP, while active transport does.

Step 3: Focus on the definition of active transport. Active transport is a process where molecules move against their concentration gradient (from low to high concentration) using a carrier protein and energy in the form of ATP.

Step 4: Compare active transport with facilitated diffusion. Facilitated diffusion also uses carrier proteins but does not require ATP because it moves substances along their concentration gradient (from high to low concentration).

Step 5: Conclude that the correct answer is active transport, as it is the only process listed that consumes ATP and uses a carrier protein to move substances against their concentration gradient.
