Diagram showing the inside of a cell and outside of a cell. There is a protein pump providing a path through the cell membrane. There are three particles outside the cell and fifteen particles inside the cell. There is a single particle approaching the protein pump and a jagged arrow labeled Energy.
What type of cell transport is modeled?
a
The model illustrates active transport because energy is required for solute particles to cross the cell membrane.
b
The model illustrates osmosis because water molecules are moving from an area of higher concentration to an area of lower concentration.
c
The model illustrates facilitated diffusion because protein channels allow solute particles to cross the cell membrane.
d
The model illustrates diffusion because solute particles are moving from an area of higher concentration to an area of lower concentration.
1 answer
The correct answer is:
a. The model illustrates active transport because energy is required for solute particles to cross the cell membrane.
This is indicated by the presence of a protein pump and the jagged arrow labeled "Energy," which signifies that energy is needed for the transport of solute particles against their concentration gradient.
