Hydrogen bonds argon extremely important in biological systems. Their presence explains galore(postnominal) of the properties of weewee. They are utilised to stabilize and determine the structure of orotund macromolecules like proteins and nucleic acids. They are involved in the mechanism of enzyme catalysis.
Properties of Water
station| Importance| Examples|
Solvent| metabolic processes in all organisms trust on chemicals being able to react together in solution.| 70-95% of cytoplasm is irrigate. Dissolved chemicals take part in processes such as respiration and photosynthesis in living organisms.|
Liquid| The campaign of material around organisms both in cells and on a large scale in mult crackpotllular organisms requires a still transport medium.| Blood in animals and the vascular tissues in plants aim water as a liquid transport medium.|
coherence| Water molecules stick to each other creating surface tenseness at the water surface.| Some small organisms make use of surface tension to walk on water.Transport of water in the xylem relies on water molecules sticking together as they are pulled up the xylem in the transpiration stream.|
Freezing | Water freezes forming ice on the surface. Water beneath the surface becomes insulated and less apt(predicate) to freeze.
| Lakes tend not to freeze completely so aquatic organisms arent killed as temperatures fall.|
Thermal Stability| Large bodies of water have fairly constant temperatures.Evaporation of water can still surfaces by removing heat.| Oceans provide a relatively stable surroundings in terms of temperature.Many land-based organisms use evaporation as a cooling mechanism, for example in panting or sweating.|
Metabolic| Water takes part as a reactant in roughly chemical processes.| Water molecules are used in hydrolysis reactions and in the process photosynthesis.|
