How does initial concentration of substrate effect enzyme activity?
At low concentration of substrate , rate of enzyme action is directly proportional to conc. of substrate .
What can effect how the enzyme and substrate come together?
Shape of substrate, shape of the enzyme, Competitive, noncompetitive and allosteric inhibitors.
Buffer and its mechanism of action?
A buffer solution works under the combined principle of common ion effect and Le Chatelier's principle
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.
In an allosteric enzyme the homotropic effect is seen when?
Ahh... A fine question. The answer: When a substrate acts as an effector there are homotropic effects. The substrate binds to the active site and induces allosteric-like effects.
What would the effect of reagent such as control buffer substrate buffer and ascorbic acid be on the browning process?
prevents food from browning
What is the use of substrate in Field Effect Transistor?
The use of substrate in Field Effect Transistors is for it to serve as insulating material between the gate and the source.

What can effect how the enzyme and substrate come together?
Shape of substrate, shape of the enzyme, Competitive, noncompetitive and allosteric inhibitors.
What effect enzymes activity?
Temperature, pH, substrate concentration
How does a substrate know to join with an enzyme?
A substrate doesn't 'know' anything. The interaction of enzymes with substrates depends on random collisions to take effect.
Effect of Diluting a buffer?
The buffer capacity increases as the concentration of the buffer solution increases and is a maximum when the pH is equal to the same value as the pKa of the weak acid in the buffer. A buffer solution is a good buffer in the pH range that is + or - 1 pH unit of the pKa. Beyond that, buffering capacity is minimal.
Buffer and its mechanism of action?
A buffer solution works under the combined principle of common ion effect and Le Chatelier's principle
How does aspirin effect yeast respiration?
Stops substrate from getting to the active site
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 is the effect of water on browning of apples?
Salt water slows the dehydration (browning of apples) because it is an acid.
What cause competition?
It slows down or even stop the enzymatic activity because it compete the actove site of the enzymes with substrate and its effect can be reduced by concentrating the concentration of substrate or add more subatrate therefore more substrate are compete with the inibitors
