Why do Asians get drunk faster and sober faster?
A larger percentage of persons of Asian decent, have a dominant gene mutation which interferes with the role of an enzyme called acetaldehyde dehydrogenase. The role of this enzyme is to convert acetaldehyde, a metabolite of ethanol (alcohol), into acetic acid. Persons with this mutation therefore experience higher levels of acetaldehyde in their systems when they consume alcohol.
What is role of metal ion in enzyme catalysis?
On each surface of enzyme there are detachable cofactor (non-protein portin of enzyme) called activators. Activators are metal ions.Enzymes are proteins and literally fold into a specific 3d structure, to make space for an active site (also called activators). Active site has a shape that fits with specific substrate molecules.The enzyme and substrate form a temporary enzyme-substrate complex.Enzymes are flexible structures.When enzyme and substrate bind together, the shape of enzyme molecule undergoes slight change.This produces strain in chemical bond in the substrate molecules and as a result these bonds break and bonds are formed. These stresses encourage a link between two substrstes leading to the formation of a different molecule.As the result of the chemicl interactions within the active sites a new chemical compound is formed. The new chemical compound is called product.This product is released from the active site, the enzyme assumes its orignal shape and is free to work again.
