SOLUTE EGG WATER MEMBRANE Figure 1. Consider figure 1. Predict how water will move across the membrane. Water will move into the cell to where there is a higher solute concentration. Water will move out of the cell to where there is a lower solute concentration. Water will move into the cell to where there is a lower solute concentration. The cell and solution are in equilibrium, so water will move both directions equally. 76 F Partly sunny arch O O O O

What is the role of lysozyme and a low ionic strength extraction buffer? Select all that apply. Cells absorb water from a low ionic strength extraction buffer, by osmosis, swell and lyse, releasing their contents Lysozyme breaks down bonds in the cellulose cell wall of plants, weakening the structure Cells release water into a low ionic strength extraction buffer by osmosis, shrink and lyse, releasing their contents Lysozyme is an enzyme found in lysosomes in cells Lysozyme breaks down bonds in the peptidoglycan cell wall of bacteria, weakening the structure Lysozyme is an antibiotic found in tears, saliva, human milk and mucus.

The cell quickly shrivels. What term describes solution X (when compared with the cell's fluid)? A saline (salt) solution is to injected into a patient. The salt/water ratio should be adjusted so that the saline solution is ____ to the patients cells. Solution Q has a higher water content that solution Z. Therefore solution Q is ___ to solution Z Solution which may cause a cell to lyse. When a cell is placed in this type of solution, there will be equal amounts of water moving in and out of the cell at equal rates.
