Fluid-mosaic Model The movement of small, lipid soluble molecules through the plasma membrane. From a high to low concentration. Diffusion The movement of water molecules through the plasma membrane.

Gases and lipid-soluble substances (such as steroids) cross by lipid diffusion; water crosses by osmosis, ions cross by facilitated diffusion; and glucose and amino acids cross by active transport. 3.

such as carbohydrates, proteins and lipids). These organic molecules are passed through food chains and eventually returned to the abiotic environment again as simple inorganic molecules by decomposers.

diffuses through the mitochondrial and cell membranes by lipid diffusion, out into the tissue fluid and into the blood, where it is carried to the lungs for removal. The hydrogen is taken up by NAD again.
