WebEnzymes are proteins, and therefore their capacity for catalysis is intimately related to a specific tertiary or quaternary molecular structure. If the tertiary or quaternary structure of an enzyme is altered, a loss of enzyme activity usually follows. Thus, environmental factors that modify protein structure also influence enzyme activity. WebHormones are secreted by endocrine glands and transported to the target cell at which the hormone acts. The hormone binds to its receptor, thereby eliciting various biological responses within the target cell. Examples of disease mechanisms that function at the different stages in the development of the insulin receptor, and result in insulin resistance, …
