Water RG

• what is water vital to?

  living organisms
• what does water make up?

  about 80% of a cell's contents
• What is a metabolic reaction?

  a chemical reaction that happens in a living organism to keep the organism alive
• what is a metabolite?

  a substance involved in a metabolic reaction
• What are the 4 main functions of water 4 ?

  
  

  1. it is a metabolite
  2. solvent
  3. temperature control
  4. water molecules are cohesive
• Explain water being a metabolite?

  Water is a metabolite in loads of important metabolic reactions, including condensation and hydrolysis reactions
• explain water being a solvent?

  water is a solvent = some substances dissolve in it

  Most metabolic reactions take place in solution (eg cytoplasm of cells) so water is essential
• explain water helping with temp control?

  it helps with temperature control because it has a high latent heat of vaporisation and a high specific heat capacity
• explain water molecules being very cohesive?

  water molecules are very cohesive (they stick together) which helps water transport in plants as well as transport in other organisms
