Biology 1.4 Water 0.0 / 5 ? BiologyBiological molecules, organic chemistry and biochemistryASWJEC Created by: DanCreated on: 05-01-14 10:03 Water molecules 'stick together' state how. Water molecules form hydrogen bonds with other water molecules 1 of 6 How does water help some reactions? It provides a medium for molecules and ions to mix as well as a medium for metabolic reactions 2 of 6 How do reactions take place in water naturally? Water has slightly positive and slightly negative parts, it will attract other charged particles such as ions and other polar units like glucose 3 of 6 How is this useful in animals and humans? It acts as a transport medium EG blood, carries many minerals and ions around the body 4 of 6 Why is a lot of energy needed to raise the temperature of water? Because the hydrogen bonds between water molecules restrict their movement 5 of 6 How is the previous helpful for living organisms? This prevents large fluctuation in the temperature of water vital for the survival of organisms 6 of 6
