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.
Can anyone help with this question Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction Is this a linear relationship What happens t?
Up to a certain point, increasing substrate concentration generally increases the initial reaction rate of an enzyme-catalyzed reaction due to more substrate molecules binding to active sites. This relationship is often linear at low substrate concentrations. At higher substrate concentrations, the reaction rate may reach a plateau due to all enzyme active sites being occupied, leading to saturation.
What is the relationship between substrate concentration and enzyme activity?
At low substrate concentrations, the rate of enzyme activity is proportional to substrate concentration. The rate eventually reaches a maximum at high substrate concentrations as the active sites become saturated.
What is the term for a reaction in which a substrate gains electrons?
A reduction reaction.
In an enzyme catalyzed reaction what is the reactant called?
The reactant in an enzyme-catalyzed reaction is called the substrate. It is the molecule that binds to the enzyme's active site and is converted into products during the reaction.
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.

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.

It acts as a reactant. In a chemical reaction A substrate is a molecule that is reacted on by enzymes.

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.
What substrate amount is required to achieve the maximum reaction rate?
The substrate concentration required for the maximum reaction rate is typically the saturation point, known as Vmax. This concentration ensures that all enzyme active sites are fully occupied by substrate molecules. The exact substrate amount may vary depending on the enzyme and reaction conditions.
What are the characteristics of an enzymatic reaction?
pH Temperature Ionic Strength Aw Substrate Concentration Substrate location.
What sentence has the word substrate in it?
The enzyme binds to its substrate in order to carry out the chemical reaction.
What is it called when and enzyme and substrate come together?
When an enzyme and substrate come together, it is called the enzyme-substrate complex. This complex is a temporary intermediate state in which the enzyme binds to the substrate to catalyze a chemical reaction.
