As you increase the substrate, rate of reaction increases, till more enzyme is available. This is called as First order kine-sis. When all the molecules of enzymes are engaged in activity, rate cannot increase further. This is called Zero order kine-sis. Alcohol is the best example for both of this.If less quantity is consumed, it is metabolized by First order kine-sis and more is consumed it is metabolized by Zero order kine-sis.

If an enzyme in solution is saturated with substate What is the most effective way to obtain yield of produtct?
If an enzyme solution is saturated with substrate the most effective way to obtain a faster yield of products is to increase the enzyme concentration. An alternative is to increase the temperature.
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.
How pro duct concentration affect enzyme activity?
Increasing substrate concentration can initially increase enzyme activity as more substrate molecules are available for the enzyme to bind to. However, at a certain point, the enzyme becomes saturated with substrate molecules and enzyme activity levels off. Very high substrate concentrations can also lead to competitive inhibition or product inhibition which can inhibit enzyme activity.
What will happen if the substrate concentration is high?
If the substrate concentration is high, the rate of enzyme-substrate complex formation will increase until all enzyme active sites are saturated, which is known as enzyme saturation. This means that the rate of reaction will no longer increase with further increases in substrate concentration because all enzyme active sites are already in use.
What is the vmax of ldh?
The vmax of lactate dehydrogenase (LDH) is the maximum velocity at which the enzyme can catalyze the conversion of lactate to pyruvate in a given concentration of substrate. This value represents the rate of the enzyme-catalyzed reaction at saturated substrate concentrations.

If an enzyme solution is saturated with substrate the most effective way to obtain a faster yield of products is to increase the enzyme concentration. An alternative is to increase the temperature.
How could you test to see if an enzyme was completely saturated during an experiment?
To test if an enzyme is completely saturated during an experiment, you can vary the concentration of the substrate while keeping the enzyme concentration constant. If increasing the substrate concentration no longer leads to an increase in the reaction rate, it indicates that the enzyme is saturated. Additionally, you can plot a graph of reaction rate against substrate concentration and observe if it reaches a plateau.
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 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.
At what time interval is the enzyme working at its maximum velocity?
The enzyme works at its maximum velocity at the substrate concentration where all enzyme active sites are saturated, known as Vmax. At this point, the enzyme is functioning at its optimum and adding more substrate will not increase the reaction rate.
How pro duct concentration affect enzyme activity?
Increasing substrate concentration can initially increase enzyme activity as more substrate molecules are available for the enzyme to bind to. However, at a certain point, the enzyme becomes saturated with substrate molecules and enzyme activity levels off. Very high substrate concentrations can also lead to competitive inhibition or product inhibition which can inhibit enzyme activity.
The binding together of an enzyme and a substrate forms a what?
enzyme-substrate complex.
What affect does too much substrate have on the rate of an enzyme reaction?
If there is too much substrate present, it can saturate all available enzyme active sites, leading to maximum reaction rate being reached (Vmax). Further increases in substrate concentration will not increase the reaction rate since all enzyme active sites are already occupied. This is known as enzyme saturation.
What to enzymes do in an enzyme-substrate?
in an enzyme-substrate complex, the enzyme acts on the substrate .
What will happen if the substrate concentration is high?
If the substrate concentration is high, the rate of enzyme-substrate complex formation will increase until all enzyme active sites are saturated, which is known as enzyme saturation. This means that the rate of reaction will no longer increase with further increases in substrate concentration because all enzyme active sites are already in use.
What happens to the rate of an enzyme controlled reaction when the substrate level is high and remains high?
The rate of the enzyme-controlled reaction will increase until all enzyme active sites are saturated with substrate. After that point, the rate will remain constant as all enzyme molecules are already actively engaged, leading to saturation kinetics.
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.
