Water

  • describe¬†and explain the properties of water that make it important in biology, including:
    • water is a metabolite in many metabolic reactions, including condensation and hydrolysis reactions
    • water is an important solvent in which metabolic reactions occur
    • water has a relatively high heat capacity, buffering changes in temperature
    • water has a relatively large latent heat of vaporisation, providing a cooling effect with little loss of water through evaporation
    • water has strong cohesion between water molecules; this supports columns of water in the tube-like transport cells of plants and produces surface tension where water meets air
