Openstax Vocabulary Ch. 6 Cell Metabolism Test

energy necessary for reactions to occur

specific region of the enzyme to which the substrate binds

inhibition by a binding event at a site different from the active site, which induces a conformational change and reduces the affinity of the enzyme for its substrate

pathways that require an input of energy to synthesize complex molecules from simpler ones

adenosine triphosphate, the cell's energy currency

study of energy flowing through living systems

pathways in which complex molecules are broken down into simpler ones

potential energy in chemical bonds that is released when those bonds are broken

small organic molecule, such as a vitamin or its derivative, which is required to enhance

inorganic ion, such as iron and magnesium ions, required for optimal regulation of enzyme activity

type of inhibition in which the inhibitor competes with the substrate molecule by binding to the active site of the enzyme

process that changes the natural properties of a substance

describes chemical reactions that require energy input

total energy of a system

measure of randomness or disorder within a system
