What else can I help you with?
Why would you expect the rate of an enzyme-catalyzed reaction to increase proportionately to enzyme concentration given an unlimited supply of substrate?
No, since the reaction reaches a max rate depending on the speed of which the Enzyme bonds to the substrate and the speed at which the enzyme catalyzes the reaction to produce enzyme and product (shown below). E + S --> ES (E - enzyme, S - substrate, P - products) ES --> E + P Thus, if each reaction rate is not equal to each other, the rate of the overall reaction is not only proportional to both the concentration of enzyme and substrate.
is it correct that the average velocity is always equal to the mean value of initial and final velocities?
No, the average velocity is calculated as the total displacement divided by the total time taken to travel that distance. It is not simply the mean of the initial and final velocities.
A concentration gradient ceases to exist when?
A concentration gradient ceases to exist when there is an equal distribution of a substance across a space or membrane. This equal distribution results in no net movement of the substance from one area to another, causing the concentration gradient to reach equilibrium.
What best describes a cell that is isotonic for a substance?
The solute concentration is equal on both sides of the cell membrane
When will the net osmosis rate equal zero in a model cell?
The net osmosis rate will equal zero when the concentration of solutes inside the cell is the same as the concentration of solutes in the surrounding solution. At this point, there will be no concentration gradient driving osmosis in either direction, resulting in no net movement of water across the cell membrane.
Is acceleration equal to initial velocity minus the final velocity divided by the time?
No, It is the average velocity.
What equals acceleration x time?
It's equal to the change in velocity (final velocity - initial velocity).
This is equal to the initial velocity plus acceleration multiplied by time?
That's the velocity at any time.
What is the formula for calculating final velocity when you know the initial speed and the acceleration?
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
Is acceleration equal to the initial velocity minus the final velocity and then divided by time?
No, acceleration is calculated as the change in velocity divided by time. It is the rate at which the velocity of an object changes. Mathematically, acceleration is represented as (final velocity - initial velocity) / time.
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 true of the values for initial velocity and final velocity if the acceleration were zero?
A change in velocity can be effected only by acceleration. Therefore, if the acceleration is zero, there is no change, so final velocity equals initial velocity.
How do you calculate the final concentration after dilution?
To calculate the final concentration after dilution, use the formula: C1V1 C2V2. This formula states that the initial concentration (C1) multiplied by the initial volume (V1) is equal to the final concentration (C2) multiplied by the final volume (V2). Simply plug in the values for the initial concentration, initial volume, and final volume to find the final concentration.
How can you find the initial velocity form the work done on a system?
To find the initial velocity from the work done on a system, you can use the work-energy principle. The work done on the system is equal to the change in kinetic energy of the system. By equating the work done to the change in kinetic energy and solving for the initial velocity, you can find the initial velocity of the system.
What does initial velocity squared plus 2 times acceleration times distance equal?
This equation represents the final velocity squared when an object is accelerating from an initial velocity over a certain distance. It is derived from the kinematic equation (v^2 = u^2 + 2as), where (v) is the final velocity, (u) is the initial velocity, (a) is the acceleration, and (s) is the distance traveled.
If two gliders of equal mass and equal and opposite initial velocity collide perfectly elastically what are the final velocities of the gliders in terms of the initial velocities?
The final velocities of the gliders after a perfectly elastic collision will also be equal and opposite to their initial velocities. This is due to the conservation of momentum and kinetic energy in elastic collisions.
How is the enzyme affected during the catalyzed reaction?
The higher the substrate concentration, the higher the rate of reaction, up till the point when the limiting factor is no longer the concentration of substrate but other factors like enzyme concentration of temperature.
