what quantity of catalase enzymes (either a concentration or a number) would be present in 1 cm cubed of celery?

 

To help a friend, so that she can work out the conc/moles & then work out the rate of reaction in terms of molecules of oxygen created per second per enzyme

hi, i don't know, but catalase has a very high rate of reaction, close to diffusion limited, ie 10^9 M-1.s-1. given a) the rate of O2 production for 1cm^3 of celery and b) the rate of reaction of catalase as 10^9 M-1.s-1 it is to simple to then calculate how many molecules of catalase there are in 1cm^3 of celery, but this may be cheating.

what quantity of catalase enzymes (either a concentration or a number) would be present in 1 cm cubed of celery?

Its hard to say, there would not be one type so it can't be tested as you would normally by measuring the amount of reactans converted in a period of time.

 

Is the question more specific?
