In physics, velocity refers to the rate at which something changes in position over time.
In biochemistry, velocity can be used to refer to the amount of product formed over time and is often used synonymously with rate of reaction. The temperature and pressure in the room won't change.
Enzymes are proteins that speed up chemical reactions by lowering the amount of energy necessary for the reaction to occur.
Enzymes bind substrate at the active site and change them into products.
The reaction rate, also known as reaction velocity, is the measure of the formation of product over time.
An enzyme rate of reaction is often calculated using the Michaelis-Menten equation, which takes into account substrate and enzyme concentration, as well as a substrate's affinity for an enzyme, known as Km.
Rates of reaction are often dependent on a variety of factors, like temperature, pressure and p H.
How fast one thing changes into another is known as the reaction rate or rate of reaction.When looking at rates, substrates and product amounts are often referred to in molar concentrations, or moles of substance per volume.Let's say you have 10 moles of ingredients in 1 bowl.How much the enzyme likes the substrate is known as the affinity, or Km, and it is calculated by looking at the rate constants of all reactions involved.The Michaelis-Mention Equation is where the initial velocity equals the Vmax multiplied by the substrate concentration and divided by sum of Km and the substrate concentration. A reaction rate is the speed at which one substance changes into another.With these factors constant, the only factor left affecting the rate is the amount of substance used or product formed.Thus, the rate of a reaction can be calculated by multiplying the rate constant by the substrate concentration (amount) or by determining reaction velocity (V).The concentration of your substrate then is 10 Molar (10M).Eventually, no matter how many additional ingredients you throw in, the electric mixer won't make cake batter any faster than it already is, unless you add yet another beater.Anyone can earn credit-by-exam regardless of age or education level.This clock representation shows some of the major units of geological time and definitive events of Earth history.
