Daniel Elleray – Group 2 – The Use of Water in Biological Systems

________________

The Use of Water in Biological Organisms.

1. Topic One: the way that water forms hydrogen bonds and links to other cells is important. Talk about how most living organisms are made up of 69% water. Link this is with temperature regulation as well as other thermal properties of water.

1. Topic Two: Talk about the importance of the cell membrane in eukaryotic cells, what it’s made up of including hydrophilic and hydrophobic phospholipids.  Explain how this is importance in cell absorption, and how the cells move and absorb nutrients using osmosis.  This might link in with cohesion/adhesion (water transport).

1. Topic Three: Talk about how proteins, carbs and lipids owe their existence to water, and how water can also be used to break them down (hydrolysis reactions)

1. Topic Four: Photosynthesis in plants, and how water is used to create energy through sunlight.

Water is considered to be one of the most important biochemical molecules on Earth, forming the majority of all living organisms. Almost 75% of the Earth’s surface is covered in water; evolutionists believe water to be the catalyst for all life where evolution has taken place for over four billion years to create all the beings that exist today. Williams [2000 p. 10] writes that 70% mass of a human cell and up to 95% mass of a plant cell comprise of water; the biological importance of this simple molecule is extremely significant as they require an aqueous environment.
