Question

ACTIVITY 2: MEASURING OSMOTIC RATES Water is essential for life. It is the solvent of living systems and is the aqueous medium in which the chemical reactions of life occur. Substances dissolved in a solvent are called solutes. substance in cells, and contains both organic and inorganic solutes. A water molecule is diffuses freely in and out of cells (mostly through water-specific protein channels called aquaporins) do not think about the "concentration" of water because it is the solvent. However, the amount of decreases as you add more solvents. For example, in "pure water there would be 100 g of water in 100 solution, but in a 1% sucrose solution 1 g of sucrose per 100g of the solution), there Water is the most abundant a small molecule that . We usually free water is only about 99 g of water in

Explanation / Answer

if the model cell h pure deionized water in cytosol, the 20% sucrose soution would be hypertonic with respect to insidde the cell.

i predict the rate off osmosis will decrease as the sucrosse concentration difference acrosss the dialysis sac increases.

the movement would be from lower to higher concentraction of solute .
