Secondary active transport uses to move something out of a

Secondary active transport uses _____________ to move something out of a cell, and later ____________ to bring it and something else in to the cell.

a. Active transport, facilitated diffusion

b. Passive transport, Active Transport

c. Active Transport, Endocytosis

d. Exocytosis, Endocytosis

Solution

a. Active transport, facilitated diffusion

Secondary active transport involves the use of an electrochemical gradient. This is a type of active transport which use the energy of established ion gradients (example, Na/K) to bring molecules across membranes to transport ions back.
