What has no effect on the rate of an enzyme-catalyzed reaction?
When an enzyme is saturated the amount of substrate added no longer as an effect on the rate of the reaction.
What affect rates does a enzyme catalyzed reaction have?
Enzymes increase the rate of reaction by changing the reaction mechanism to one with a lower activation energy.
Describe the roles of a catalyst and substrate in a chemical reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction. Catalysts work by lowering a reaction's activation energy.A substrate is a reactant of an enzyme-catalyzed reaction.
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?
The more substrate the faster the rate of reaction up to a point where it levels out. Basically the enzymes and substrates bounce around until they meet the substrate that the enzyme can catalyse so obviously with more substrate there's more chance of he enzyme bumping into the right substrate
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.

What happens when an enzyme catalyzes a reaction?
The rate of a reactions usually increases when catalyzed by an enzyme. For maximum rate of activity, the enzyme needs optimal conditions.
As temperature decreases the rate of an enzyme-catalyzed reaction also decreases why?
Just like many other chemical reactions, the rate of an enzyme-catalyzed reaction will decrease with temperature because of the decrease in the number of high energy collisions between particles.

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.

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.

How does the non-competitive inhibitor decrease the rate of an enzyme reaction?
Noncompetitive inhibitors decrease the rate of an enzyme reaction by bonding to an enzyme somewhere other than the active site, deforming it and permanently disabling the enzyme, so that enzyme can never function again, so the rate of reaction decreases.
Is facilitated diffusion similar to an enzyme-catalyzed reaction?
Both have similar kinetics, meaning the mechanism by which they work is similar. In facilitated diffusion, a ligand moves through a membrane through a channel. If the concentration of ligand increases, the rate of diffusion increases until the channel becomes saturated and can work no faster. If the concentration of channel increases, the rate increases until the ligands become "saturated". Enzyme catalyzed reactions work similarly, except they are not moving through a membrane. If the ligand increases in concentration, the rate of reaction increases until the enzyme becomes saturated. If the enzyme concentration increases, the rate of reaction increases until all the ligands become "saturated". Facilitated diffusion is basically a protein enhanced transport system, just like an enzyme reaction is basically a protein enhanced metabolic system. Same math, same graphs, same mechanism, same components.
