BioFlix Quiz – Membrane Transport
Write the answer to each question in the blank. Note that the order of the answer options does not match
the online version of the quiz.
____1. In active transport,
A. no energy input is required from the cell.
B. molecules move across the plasma membrane against their concentration gradient.
C. a vesicle inside the cell fuses with the plasma membrane and releases its contents outside the
cell.
D. the plasma membrane forms a pocket that pinches inward, forming a vesicle that contains
material from outside the cell.
E. molecules move across the plasma membrane by crossing the lipid bilayer directly, rather than by
using a transport protein.
