A<unk>  response curve showing the normalised tissue response to stimulation by an agonist. Low<unk> s are insufficient to generate a response, while high<unk> s generate a maximal response. The steepest point of the curve corresponds with an EC50 of 0.7 molar The<unk> , or exposure–response<unk> , describes the magnitude of the response of an organism, as a function of exposure (or<unk> s) to a stimulus or stressor (usually a chemical) after a certain exposure time.<unk> s can be described by<unk><unk> response curves. This is explained further in the following sections. A stimulus response function or stimulus response curve is defined more broadly as the response from any type of stimulus, not limited to chemicals.
