Explain the relationship between the properties of water and its uses in living organisms as a coolant, medium of metabolic reactions, and transport medium
Water acts as a coolant in organisms when they sweat. Because water has a high amount of vaporization, when organisms sweat, it evaporates and it takes the heat with it. Thus, making the organism cooler. Water in the body maintains a relatively normal body temperature to keep the proteins from losing their shape
- Water can act as a transport medium because it is cohesive. Because the water can bind to itself, and all the molecules are bonded to one another, it allows for the transport of water against gravity
- Ex) Water up a straw, Water being drawn up the xylem of plants (transpiration)
Water is a universal solvent because it can dissolve polar and ionic bonds. In order for reactions to occur, the molecules have to be dissolved. The dissolved molecules can react in the cell because the cell is mainly made up of water. In this way, water acts as a medium of metabolic reactions.
