Transports Across The Plasma Membrane
Transport Across The Plasma Membrane
Intracellular Fluid (ICF) – The two thirds of your body fluid contained inside body cells. (Intra = within). The cytosol of the cell.
Extracellular Fluid (ECF) – Fluid outside the body cells. (extra = outside).
Interstitial Fluid – The ECF in tiny spaces between cells (inter = between).
Plasma- the ECF in blood vessels.
Lymph- The ECF in lymphatic vessels.
Solute – Any material dissolved in fluid.
Solvent- The fluid a Solute is dissolved in.
Concentration – The amount of a solute in s solution.
Concentrate gradient – A difference in concentration between two different areas.
Passive Processes – When a substance moves its concentration through the membrane, using only kinetic energy.
Active Transport - when cellular energy pushes a substance through the membrane against its concentrate gradient.
Vesicles – Another way some substances can enter and leave the cell.
*Passive processes Diffusion: The Principle
Diffusion – When molecules and ions level out concentration.
Equilibrium – When the substance is evenly spread out through the substance and the concentration gradient disappears.
Simple Diffusion – Substances diffuse across the membrane in one of two ways:
Lipid-soluble substances diffuse through the lipid bilayer.
Ions diffuse through the pores of ion channels formed by integral proteins.
Facilitated Diffusion – When substances that cannot diffuse through the lipid bilayer or ion channels and travel across the plasma membrane.
*Osmosis
Osmosis – When water molecules move concentration to level out.
Osmotic pressure – The pressure forced upon the membrane by a solution with a solute that cannot pass through.
Isotonic Solution – A solution where the concentrations of solutes that cannot pass through the plasma membrane are the same on both sides.
Hypotonic Solution – A solution that has a lower concentration of solutes than the cytosol inside red blood cells.
Hemolysis – The
