What factors affect the movement of materials in and out of cells?
1 Answer
Knowing the categories of factors is a good first step to knowing the factors.
Explanation:
Physical aspects, such as temperature of the system, can affect how fast the particles are moving. At higher temperature, particles move faster.
Chemical factors, such as concentration differences (gradients) and electrical charges, can influence how much, and how fast, the substances will move. An electrochemical gradient (a combination of both concentration differences and electrical charge differences) can powerfully influence the movement of particles into or out of a cell across its membrane.
The membrane of a cell can have channels or carriers, protein conduits that allow specific particles or classes of particles to pass in one-way or two-way paths through the membrane.
