question 23 of 25 simple diffusion facilitated diffusion primary active transport secondary active transport answer bank movement of solutes out of the cell against their concentration gradient using atp - powered membrane pumps movement of one solute out of the cell, against its concentration gradient, via a cotransporter driven by another solutes gradient movement of solutes out of the cell down their concentration gradient using membrane proteins movement of solutes out of the cell directly through the plasma membrane

Explanation:

Simple diffusion is the movement of solutes directly through the plasma membrane down their concentration gradient. Facilitated diffusion uses membrane - proteins to move solutes down their concentration gradient. Primary active transport moves solutes against their concentration gradient using ATP - powered membrane pumps. Secondary active transport moves one solute against its concentration gradient via a cotransporter driven by another solute's gradient.

Answer:

Simple diffusion: movement of solutes out of the cell directly through the plasma membrane
Facilitated diffusion: movement of solutes out of the cell down their concentration gradient using membrane proteins
Primary active transport: movement of solutes out of the cell against their concentration gradient using ATP - powered membrane pumps
Secondary active transport: movement of one solute out of the cell, against its concentration gradient, via a cotransporter driven by another solute's gradient
