    Hi everyone

    I was wondering whether someone could tell me about the exponential growth rate constant and where to find the formula on the net

    Thanks

    exponential growth rate constant is growth being equal to size. Therefore it should be 1 and be a constant!

    ie if size doubles, then growth doubles. If size halfs then growth is halved...

    erm you mean the formula

    k = (Log10(Nt) - Log10No) / (0.301 x t )

    k is the generation of cells per hour
    and the recriprocal is the time needed for the cells to double..

    erm...was that the answer you wanted?

    Sally it's really not that important. If it does come up in the exam we will be provided with the formula and a brief explanation of how to use it and then you just stick no's in calculator! So as long as you know how to use Logs (which I'm praying you do as P3 is a week on wed!!!!) then you'll be fine. Half the stuff, mainly sheets!, we've been given for biology (particularly micro-bio) is really useless! lol
