the enzyme lab?

Question

I have few questions..

how can i explain the differences in the reaction rates..
and can H2O2 be broken down by catalysts other than thoses found in living systems..?
lastly, what's the difference between the rates of reaction with potato as compared to liver..?

well, for the last question, i know in liver there is a catalase..but what does it do..?does it make the reaction faster..?

Answer 1

how can i explain the differences in the reaction rates..
and can H2O2 be broken down by catalysts other than thoses found in living systems..?
yeah - some metals and metal compounds catalyse h2o2 breakdown



lastly, what's the difference between the rates of reaction with potato as compared to liver..?

well, for the last question, i know in liver there is a catalase..but what does it do..?does it make the reaction faster..?

catalase? in liver there is blood and hemoglobin with iron doing the trick. and faster than the potato catalase. do this test - the tiniest ammount of blood will speed the reaction too

enzymes as well as other catalysts are here to make reactions faster, that is it. simplified explanation: they do it by using the shape of their molecules to either get the reaction partners together in case of synthesis reaction or pry apart the molecule in case of brakdown reaction
