Thanks alott but what about the substrate binding to the active site even though non competitive inhibitor alters active site so substrate cannot bind.
Non-competitive inhibition models a system where the inhibitor and the substrate may both be bound to the enzyme at any given time. When both the substrate and the inhibitor are bound, the enzyme-substrate-inhibitor complex cannot form product and can only be converted back to the enzyme-substrate complex or the enzyme-inhibitor complex.

Find number of eyepiece graticule between two stage micrometer scales.Then from that,find value of 1 eype piece and when you find value of 1 piece just measure number of eyepiece the plant cell is and multiply by the value which you found for 1 piece

Thanks :)

Need help.
I don't get resolution and what size will be viewed under what resolution :-/


View attachment 63911
if object has higher size then resolution stated it can be seen.
0.25 micrometer is 250 nm .
So as both pandoravirus and mimivirus are more then 250.They will be seen.
typical virus is 20-150 so it will not be seen by light but will be seen by electron I am in a hurry so is my answer right?
Answer is A
