3H is an isotope of hydrogen which has 2 neutrons...the same no as 4Hehttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_s11_qp_12.pdf
Please explain question no.1 ... The answer is B
Thank you
Ohh well thank you soo much ..
3.5 x .005= .0175 mm = 17.5 um. Are you sure it's not C?
it is C... btw what if i do this method----> 0.005*1000 = 5 after that --> 5*3.5=17.5 this is also right...
Thank you..and yeah it is C .. Was Lukin at the wrong paper :/
Well I got the same intensity of shock..when I saw B .. Which was probably the wrong paper!i was too shocked that how can B come?
It doesn't mean that they can dissolve...it means that they're allied to move freely through the liquidOne question ...
Enzymes are soluble in water ?
If yes, then HOW! As in If they are soluble..won't they just dissolve in what ever solution is there..and how would they then form the so called *enzyme substrate complex* ?
simple it is told that there are 19 base pairs right..
You're right.
Competitive inhibitors can be overcome by increasing substrate concentration.
But if the substrate concentration doesn't increase then neither does the maximum RATE of reaction right? I'm sorry it's a little confusing, cause noncompetetive inhibitors don't reduce the MAXIMUM rate of reaction either
maximum rate wouldn't increase either .. Cuz if only u inc the substrate con. Then there are more chances of the substrate to bind with the enzyme ... And if the substrate con ain't increasing then.. The rate would stop as in no further reaction.
