Question

the cell
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 and requires energy. Endocytosis and exocytosis are types of active transport where large molecules or bulk amounts of substances are moved into (endocytosis) or out of (exocytosis) the cell.

Answer:

l. passive
