Which of the following accurately describes an example of how materials can move across the cell membrane through active transport? a protein acts as a channel to allow large, hydrophilic molecules to diffuse across the cell membrane. a protein acts as a pump and moves calcium ions from an area of low concentration to an area of high concentration. the cell membrane folds to surround a substance and bring the substance inside the cell during exocytosis. water moves by osmosis from higher concentration to lower concentration by passing through proteins called aquaporins.
