What would happen to the rate of a reaction if the concentration of substrate was increased after the point of saturation?
zff
Why was there no increase in the reaction rate with 8.0 g. of substrate as compared to 4.0 g. of substrate What would you need to add to see an increase in the reaction rate with 8.0 g. of substrate?
because the amount of the other variables are the same, no change. once 4.0 g of lactose substrate or whatever it is is at it's maximum reaction rate, it can do no one reaction therefore there was no reaction in the 8.0 g of substrate. Because the reaction volume was also doubled; so there was no change in concentration of substrate.
What is true of substrate?
It acts as a reactant. In a chemical reaction A substrate is a molecule that is reacted on by enzymes.
What is the difference between a reactant and a catalyst?
A reactant is consumed in a reaction to make products. A catalyst is not consumed during the reaction. It is either not directly involved in the reaction or regenerated upon the end of the reaction. This is the main difference. In addition, catalysts work by decreasing the activation energy for the reaction, allowing the reactants to react more easily.
How does a enzyme increase the rates of reactions?
An enzyme increases the rate of the reaction by lowering the activation energy needed for the reaction. The secret is that enzymes weaken the bonds in the substrate so that products are formed much faster. Enzymes are catalysts or substances that speed up the reaction (without being consumed in it). An enzyme increases the rate of reaction by lowering the energy of activation or (Ea). Enzymes achieve that by attaching to the substrate in the active site and forming an enzyme substrate complex in which the enzyme disturbs the covalent bond of the substrate. This causes it to enter the transitional state, which is the most energetic and unstable state. The enzyme then breaks apart, and the substrate goes into an exorganic reaction to form the product.
Why does it happen enzyme after it participates in a reaction?
After the enzyme has converted the substrate to the product, it is now free to accept more substrate. The enzyme does not get changed or altered in a reaction.

In an enzyme catalyzed reaction what is the reactant called?
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.

Because the reaction volume was also doubled; so there was no change in concentration of substrate.
What would happen if an active site was blocked by another molecule?
The substrate would be unable to bond preventing the reaction from being catalyzed.
Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction Is this a linear relationship What happens to the initial reaction rate as sub?
As the substrate concentration increases so does the reaction rate because there is more substrate for the enzyme react with.

What is nucleofugacity?
if in a reaction the leaving group of the substrate is electron dense , it is called nucleofuge. The ability of nucleofuge to leave the substrate in a reaction is called its nucleofugacity .
What are the characteristics of an enzymatic reaction?
pH Temperature Ionic Strength Aw Substrate Concentration Substrate location.
The reactants in an enzymatic reaction are called what?
In a chemical reaction the actual reactants are also called the starting materials or interactants. These are the materials necessary for the reaction to happen and undergo chemical change.
