Document Summary
The cell main parts in the cell: cell (or plasma membrane, cytoplasm, cytosol, organelles, nucleus. Outside of the cell: the extracellular space, the cells that compose the organs of our body are embedded within the extracellular material of connective tissue. Body fluids are divided into an intra and extracellular compartment: intracellular compartments (~67%, extracellular compartments (~33%, 20% of vascular fluid (blood plasma, 80% as interstitial fluid (non-vascular tissue fluid ) Gradient for solute must exist across the membrane: *solute must be osmotically active (membrane nearly impermeable to solute but is permeable to the solvent) In this case na+ and glucose are osmotically active : what would happen with the example above, osmosis, net movement of water from left to right, adding more water makes it less concentrated, partition (divider) moves to left. Mgcl2 has a molecular weight of 95 g/mol. You want to create 350 ml of a 0. 2 m. Kbr has a molecular weight of 119 g/mol.
