What does a limiting factor in case of a enzyme do?
A limiting factor limits the growth or development of an organism, population, or process.In biological or ecological terms, a limiting factor causes a population to decrease in size so following that logic I would say a limiting factor slows down or decreases the activity of an enzyme in a biological reaction..
@Franklin447 So can I say "It prevents the rate of reaction from increasing".
exacly :)
exactly*
Why is it so?
ok I am going to use the enzyme itself as a limiting factor to explain this to you hope you dont mind
ok please
what happens in a reaction involving an enzyme when u add more enzymes??
reaction becomes faster
yes reaction becomes faster. Do you know why reaction becomes faster?? and as the reaction becomes faster what happens to the substance the enzyme is reacting on?
yes there are less substrate in ratio to enzymes.
excellent so from what u have told me I can assume u know that as the the reaction carries on the substrate decrease. You can add more enzymes and the rate will keep on increasing up to a point of saturation. At this point the rate will no longer increase but stay the same and if u recall its also still acting on the deminishing numbers of the substrate therefore as the substrate decreases the reaction rate also decreases and less numbers of enzyme are needed but we already have a saturated solution so the remaining enzymes that are not needed for the reaction acts as the limiting reactants and thus drives the reaction rate even lower
