Question: Below is a diagram of the mechanism of a general enzyme-catalyzed reaction. Put the labels in the correct locations. The abbreviations E, P, ... The enzyme's role in the reaction is of biocatalyst. All the reactions, which can otherwise take place if provided with enzyme, simply increase their speed. Enzymes can speed up the reaction rate but they cannot force a reaction to take place. The mechanism involved in the reaction remains the same enzymes only speed up the process.

Catalytic Mechanism. In most cases, the hydrolysis of the glycosidic bond is catalyzed by two amino acid residues of the enzyme: a general acid (proton donor) and a nucleophile/base [].Depending on the spatial position of these catalytic residues, hydrolysis occurs via overall retention or overall inversion of the anomeric configuration.

Electron Transport Chain Definition. The Electron Transport System also called the Electron Transport Chain, is a chain of reactions that converts redox energy available from oxidation of NADH and FADH 2, into proton-motive force which is used to synthesize ATP through conformational changes in the ATP synthase complex through a process called oxidative phosphorylation. Given the oxygen dissociation curves, which of the following statements ... Complete the diagram of the mechanism of a general enzyme-catalyzed reaction. Gluconeogenesis refers to a group of metabolic reactions, some of them highly exergonic and irreversible, which are regulated both locally and globally (by insulin, glucagon, and cortisol). The purpose of this system, localized in both the cytosol and mitochondria, is to maintain blood glucose level constant throughout fasting state. The balance between stimulatory and inhibitory hormones ... This reaction is unique to gluconeogenesis and is the first of two steps required to bypass the irreversible reaction catalyzed by the glycolytic enzyme pyruvate kinase. In the cytosol, oxaloacetate is decarboxylated and rearranged to form phosphoenolpyruvate (PEP) via the enzyme PEP carboxykinase.
