The curve describes the initial rate of product formation at a fixed enzyme concentration when the substrate concentration is varied on successive trials.

These helper-molecules are called cofactors. Cofactors are non-protein molecules that bind to the enzyme and contribute to reactions in a number of different ways. Co-factors can either be inorganic ions, such as the Zn 2+ …Abstract. Enzyme kinetics is arguably the most time and cost effective way to study enzymes. It is the primary way to study enzyme catalysis, because no other approach allows one to test whether a chemically or spectrophotometrically detected intermediate is formed and turned over on the catalytic timescale.In this study, the enzyme alcohol dehydrogenase (ADH) is used to catalyze the conversion of ethanol (the substrate) to acetaldehyde (the product). Eight kinetic trials were carried out in a pH 9.0 buffer; only the concentration of ethanol was varied from one trial to the next. The reaction was followed spectrophotometrically, although in an ...
