Several factors can influence the maximum response of an organism to a chemical substance:
Receptor Availability: The number of available target receptors can limit the maximum response. Biological Variability: Differences in genetic makeup, age, sex, and health status can lead to variability in responses. Route of Exposure: The route of exposure (oral, inhalational, dermal) can affect the absorption and distribution of a substance, influencing its maximum effect. Environmental Factors: Conditions such as temperature, pH, and presence of other chemicals can alter the maximum response.
