Question

which type of transport moves down the concentration gradient? i. active j. endocytosis k. exocytosis l. passive

Explanation:

Passive transport moves substances down their concentration gradient (from an area of higher concentration to an area of lower concentration) without the use of energy. Active transport moves substances against the concentration gradient (from lower to higher concentration) and requires energy. Endocytosis and exocytosis are types of active transport for bulk movement of substances into (endocytosis) or out of (exocytosis) the cell.

Answer:

l. passive
