In the study of enzyme kinetics, the units Km and Vmax are measurements used to represent the rate of enzymatic reactions. Typically Vmax represents the maximum reaction rate achieved by the system, while Km is the substrate concentration at half the reaction rate of Vmax.Know More
Enzyme kinetics is an essential part of biochemistry because enzymes are the protein catalysts that speed the rate of chemical reactions. The effect is achieved as the enzyme temporarily binds to the substrate and lowers the amount of activation energy required to convert the chemical.
Enzyme conversion rates are influenced by several other factors, including the concentration of substrate molecules, the presence of inhibitors and the temperature of the solution. The study of these rates is known as enzyme kinetics.
The system of measurement used is known as Michaelis-Menten kinetics, and it is named for the German biochemist Leonor Michaelis and the pioneering Canadian physician Maud Menten, who both made significant contributions to the study of enzyme kinetics and histochemistry.Learn more about Measurements
The standard unit for resistance is called the ohm after the German physicist Georg Ohm. Its symbol is the capital Greek letter Omega in the International System of Units and is the letter “R” in the British system of measurement.Full Answer >
A gravitational constant has a value of 6.673 84 x 10^-11 m^3 kg^-1 s^-2 in English units, which can also be written as G = 6.673 x 10^-11 N m^2 kg^-2. This is also called the Newtonian constant of gravitation.Full Answer >
The MKS system of units is the precursor metric system of the contemporary International System of Units, which is commonly referred to as SI, from the French Le Systeme Internationale d'Unites. The initials MKS stand for meter, kilogram and second, which are three fundamental units of measurement.Full Answer >
The common term of measurement for luminosity is watts. Luminosity is the measure of brightness and the amount of energy a star or light emits per second. The measurement is an intrinsic measurable property that can be made independently of distance.Full Answer >
