i will rep anyone who helps!!!

this is my results after doing my investigation on temperature with yeast.
Temperature, Rate of reaction, Q10
10, 0.47, 0.47
20, 0.73, 1.55
30, 3.12, 6.64
40, 7.87, 2.52
50, 16.13, 2.05

is the q10 correct.? if so what does it explain. thank you. i will rep anyone who helps!

Are the two results supposed to be the same (ie repeats)?

Q10 will not work perfectly over all temperature ranges. It is just an empirical law that tends to work for most biological enzymes over the "normal" temperature range.

Just looking at your first column of results over the 30-50 temp range, it seems that for every 10 degree rise, the rate does roughly double (within experimental error).

You can show this by dividing one rate by another (eg 16.13/7.87) and expect an answer close to two.

However your second column of results certainly doesn't follow Q10 over this range, because the rates decrease. It would be nice if this was another enzyme you were investigating, because you could say this enzyme was denatured in this range.

If Q10 is followed it doesn't really "tell you" anything other than it works! It isn't a fundamental law that shows anything really - it just shows the rate is increasing exponentially over this range.
