i have carried out an experiment to see which tissue (either heart, muscle or liver)has the most catalase enzymes. i have found out that the heart has very few catalase enzymes compared to a muscle tissue from the back thigh of a lamb. And the lamb's liver has the greatest amounts of catalase enzymes out of the three. i have struggled to find the reason for this or the exact explanations of this. will u be able to give me some suggestions please? does it have anything to do with haemoglobin carrying oxygen and the production of superoxide wen metHB is formed?? or is it that the blood carries these toxic substances and for which the liver will "filter" therefore catalase enzymes are needed in the liver to break down hydrogen peroxide?? another part to my study was that the body's ability to produce catalase-SOD enzymes decrease with age...and thats what my experiment showed...but why ?!? anything to do with free radicals?? i would appreciate it very much if u would please answer me with some suggestions to why these cases are as such. thank you very much..
