After a reaction, the substrate is transformed into products through the interactions with enzymes or other catalysts. The original substrate molecules undergo chemical changes, resulting in new molecular structures that have different properties. Once the reaction is complete, the products are released, and the enzyme, if involved, can often be reused for subsequent reactions. The fate of the substrate ultimately depends on the specific reaction conditions and the nature of the substrates and products involved.

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 a substrate reaction?
A substrate reaction refers to a chemical reaction that occurs when a substrate, typically a molecule or compound, interacts with an enzyme or catalyst. During this process, the substrate undergoes a transformation, resulting in the formation of products. The specificity of the reaction depends on the enzyme's active site, which binds to the substrate, facilitating the conversion through various mechanisms such as breaking or forming chemical bonds. This concept is fundamental in biochemistry and enzymology, illustrating how enzymes catalyze biochemical reactions.
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.
How does an enzyme catalyze a reaction and what mechanisms are involved in this process?
An enzyme catalyzes a reaction by lowering the activation energy required for the reaction to occur. This allows the reaction to happen more quickly and efficiently. Enzymes achieve this by binding to the substrate molecules involved in the reaction and stabilizing the transition state, making it easier for the reaction to proceed. This process involves mechanisms such as induced fit, where the enzyme changes its shape to better fit the substrate, and active site binding, where the substrate is held in a specific orientation for the reaction to occur.
What is substrate concentration?
Substrate concentration refers to the amount of substrate present in a chemical reaction. It is a key factor that influences the rate of a reaction, as higher substrate concentrations typically lead to an increase in reaction rate until the enzyme becomes saturated.
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 would happen if an active site was blocked by another molecule?
If an active site is blocked by another molecule, it could prevent the substrate from binding to the enzyme, inhibiting the enzyme's function. This can lead to a decrease in the rate of the enzymatic reaction or complete inhibition of the reaction.
Increasing the substrate concentration in an enzymatic reaction could overcome what?
Increasing the substrate concentration in an enzymatic reaction could overcome low reaction rates due to insufficient substrate molecules available for the enzyme to bind to, thereby accelerating the reaction rate. This is known as the substrate concentration effect, where higher substrate concentrations can lead to higher reaction rates until the enzyme becomes saturated.
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 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 a true substrate?

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.
