what type of transport takes place when a protein allows an ion to enter a
cell, but no additional energy is needed to make this happen?
a. active
b. facilitated
c. osmosis
d. endocytosis

B. Facilitated

Explanation:

Facilitated diffusion is a type of passive transport that allows certain molecules into the cell, which means they do not use energy. Because the cell membrane is hydrophobic, molecules that are polar cannot pass through as easily. For them to pass, they diffuse through transport proteins that are found throughout the membrane.
