The binding curve of oxygen and hemoglobin is sigmiodal for a patient with carbon monoxide poisoning. B. 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.

Box 1 shows a hypothetical dose-response curve, highlighting some of the important … WebLocally Affect Membrane Binding ... To parametrize the dependence of b on ρ, we used sigmoidal curves (Figure 2) of the form f(ρ)=A/(1 + exp(−k(ρ − I))), where A is the amplitude, I the inflection point and k the steepness of the fitted function (parameters see Table S6).

WebSummary. Sigmoidal growth is a modification of exponential growth in which the percent change gets smaller as the population approaches the carrying capacity. The current growth rate is the product of the initial growth rate and the percentage of resources available. Initially, there are 100% of the resources available, so the sigmoidal growth ...

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.
