Example text

In such cases we call the smaller molecule a ligand. A ligand is a smaller molecule or atom that binds to a larger molecule. The smaller molecule may be integral to the biological purpose of the larger molecule, or it may simply serve to activate or deactivate the larger molecule in carrying out its purpose. When hemoglobin carries oxygen from the lungs to all of the cells in our body, oxygen molecules bind to the hemoglobin in the lungs. Later, the oxygen is released from the hemoglobin, so it can be used inside our body’s cells.

Allostery allows two things to take place: allosteric regulation and cooperativity. The control of a biological process by a cell or organism is called regulation. In many biochemical processes, one particular part of a protein molecule is directly involved in carrying out that protein’s function (see also the section Structure Function Relationships ). That part is known as the active site of the protein. Many biological processes involve binding or some other interaction between molecules at the active site.

Obviously we want experiments to agree with our ideas of how the physical universe behaves. But it’s even more important to design experiments that attempt to prove that our model is wrong! If we design an experiment to disprove our model and it fails to do so, this is a stronger support of the model than an experiment designed to agree with the model. Good experimental design allows us to consider a model “correct” in the sense that the model accurately predicts the results of future experiments and can be used as a tool to manipulate living things and biomolecules as we choose.
