Quizplus · Accepted Answer

The only option that fits the given description is active transport, which involves movement of substances from lower to higher concentration with the help of a specific protein carrier and the input of energy. Facilitated diffusion and diffusion involve movement from higher to lower concentration and do not require energy input. Osmosis is the movement of water across a semi-permeable membrane and does not necessarily require a protein carrier or energy input. Endocytosis involves the engulfment of substances by the cell, which is not specified in the given question.
