Without knowing the enzyme you are interested in, it is hard to give an exact answer. It all depends on the amount of the substrate, temperature, the resultant product, whether either is involved in a chain reaction or a simple reaction and if there is a co-enzyme involved.

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.
The initial rate of an enzyme catalysed reaction depend on?
Based on Michaelis-Menten enzyme kinetics, the initial rate of reaction, vi, is dependent on maximum rate Vmax, substrate concentration [S], and the enzyme's Michaelis constant Km, which represents the the tendency of the substrate/enzyme complex to dissociate. The dependence on enzyme concentration is factored into the maximum rate. The equation to describe this is: vi = Vmax([S]/(Km+[S])) Follow the link below for details.
What is the function of an enzyme?
The function of an enzyme is to increase the rate of a reaction.
What can Tobin conclude about the relationship between the enzyme concentration and the reaction rate in the presence of excess substrate?
There is a direct relationship; as the enzyme concentration increases, the rate of reaction increases.
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.

What happens to the rate of enzyme concentration when you increase substrate concentration?
The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant.
Why might heating an enzyme slow the rate at which the rate occure?
when heating it it prevents the enzyme from adapting faster and that takes time for the enzyme to adapt which will take more time and make the rate at which the reaction occurs slower. did i answer ur question? :)

What is the maximum initial reaction rate for this enzyme at pH7?
It's 350 - I'm n biology HNRS
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 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.
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.
What measures of how fast reaction occurs?
The measure is the rate of reaction.
What is the function of an enzyme?
The function of an enzyme is to increase the rate of a reaction.
What should be done in order to keep the rate constant over the entire time course?
add more substrate. The rate of the reaction drops when the enzyme no longer has a maximum number of substrate molecules to interact with. Above the maximum substrate concentration, the rate will not be increased by adding more substrate; the enzyme is already working as fast as it can. An enzyme can catalyze a certain number of reactions per second, and if there is not sufficient substrate present for it to work at its maximum velocity, the rate will decrease. Therefore, to keep the enzyme working at its maximum, you must add more substrate.

There is a direct relationship; as the enzyme concentration increases, the rate of reaction increases.
