Question 1 of 5
Which transport mechanism involves cellular energy?
Correct Answer: B
Rationale: The correct answer is B: Active transport. Active transport requires cellular energy in the form of ATP to move molecules against their concentration gradient. This process involves specific carrier proteins embedded in the cell membrane that actively pump substances across the membrane. On the other hand, Filtration (
A) is a passive process driven by pressure gradients, Diffusion (
C) is a passive process where molecules move from high to low concentration, and Osmosis (
D) is the movement of water across a semi-permeable membrane without energy input. In summary, active transport is distinct in its requirement for cellular energy, making it the correct choice in this scenario.
