What else can I help you with?
True or false in a cell that has an abundance of substrate does increasing the enzyme concentration will not affect the number of reactions occurring in the cell?
False
Increasing the substrate concentration when there is less substrate than enzyme?
A for Plato users
Why will increasing the substrate concentration not decrease the effect of a non competitive inhibitor?
Because you will still have the same number of enzymes inhibited. For example, you have 20 enzymes and 10 non-competitive inhibitors. Regardless of substrate concentration, at any one time, there will only be 10 enzymes available to accept a substrate. Increasing the substrate concentration does not affect this.
How does increasing substrate concentration affect the rate of enzyme action when the enzyme concentration remains constant?
It doesn't
How does increasing enzyme concentration affect the rate of enzyme action when substrate concentration remains constant?
It doesn't
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.

What does your data indicate about the optimum substrate concentration for this lactase catalyzed reaction?
The data indicates that the optimum substrate concentration for the lactase-catalyzed reaction is typically at a concentration where the enzyme active sites are mostly saturated with substrate molecules, leading to maximum reaction rate. Beyond this point, increasing substrate concentration may not significantly increase the reaction rate due to enzyme saturation. This optimum concentration ensures efficient enzyme-substrate binding and catalytic activity.
How does concentration of substrate affect enzymes work?
They do so because it is in theiq characteristics to. They are catalysts so they are generally protenious in nature(hence promote growth)or speed up the rate of chemical reactions. Nevertheless,some catalysts slow down Chemical reactions.
When substrate concentration is much greater than Km the rate of catalysis is almost equal to?
the maximum catalytic rate (Vmax). At this point, all enzyme active sites are saturated with substrate and increasing the substrate concentration will not further increase the rate of catalysis.
What would be the likely outcome if you increased the concentration of substrate for an enzyme in the presence of a noncompetitive inhibitor?
Increasing the concentration of substrate will not overcome the effect of a noncompetitive inhibitor. The inhibitor binds to the enzyme at a site other than the active site, causing a conformational change that reduces the enzyme's activity. Therefore, increasing the concentration of substrate will not result in a significant increase in enzyme activity.
What may inhibit enzymatic reactions EXCEPT?
Enzymatic reactions can be inhibited by factors such as temperature, pH, and the presence of inhibitors that bind to the enzyme or substrate. Additionally, substrate concentration can also affect reaction rates; if substrates are in low supply, it may limit the reaction. However, an increase in enzyme concentration typically does not inhibit enzymatic reactions; instead, it usually enhances the reaction rate, assuming sufficient substrate is available.
