Web1 Answer. The reason is to make it easier to determine a suitable dose from the graph. Normally, using a arithmetic scale, the response curve is a hyperbolic, with most of the information squished together in a small section of the graph. By using the log the function usually becomes somewhat sigmoid, with a relatively linear section in the ... WebJan 10, 2012 · Where he has met them I don't know. But he could have met them in positively co-operative binding curves, e.g. of oxygen to haemoglobin or other ligands to certain proteins. These have often been called 'sigmoid' although actually sigmoidicity is not the same as co-operativity but strongly co-operative curves are sigmoid.
