Chemical Sensitivity Due to Genetic Differences
... by a two step process: Alcohol is first converted to acetaldehyde by an enzyme called alcohol dehydrogenase (ADH). This enzyme consists of two subunits. The subunits are encoded at five different gene locations ... Indians, 0% (3). Next, acetaldehyde is broken down to acetic acid and water by an enzyme called acetaldehyde dehydrogenase 2 (ALDH 2). It has a high affinity for acetaldehyde and will ...

... ? h) In addition to being phosphorylated by hexokinase, glucose may also be phosphorylated by an enzyme called glucokinase. Glucokinase has a much higher KM for glucose than does hexokinase. Given that the ... complex G-HK = Glucose-hexokinase complex According to the Michaelis-Menten model of enzyme kinetics, the fraction of enzyme involved in ES complexes is: The problem asks for the ratio of [G ...
