After some important cellular processes, there is an abundance of Carbon Dioxide molecules inside a cell, and not enough outside of the cell. Carbon Dioxide molecules would because there is a concentration outside the cell than inside the cell.
A molecule needs to enter into the cell but cannot go through the plasma membrane because of its polarity. However, the molecule can bind to a protein and the protein changes shape to allow the particle to move through the membrane.
Which of the following is not a factor that affects the rate of diffusion?
How would you expect oxygen molecules to move if more oxygen molecules were outside of a cell.
A molecule that is important for cell functioning cannot diffuse through the plasma membrane, but needs a protein that can open and close to allow the molecule to diffuse. What is this protein called?
