Molecular Shape and Functions
The shape of a molecule often relates to its function.
Examples show this trend.
Enzymes – help to speed up reactions by bringing reactions into contact with each other
Water – very important for cells to live
- Molecules are small enough to fit through cell membranes so energy is not used to transport water
- The polarity of water makes it easy to transport
- Polarity lets it be a good solvent in the body
Lipids Storing energy
Have lots of bonds to store energy.
