If your pet has orange colored pee, additional blood and urine tests need to be performed immediately. What if my dogâs urine is red, pink, red/brown, or red/orange urine Red or pink urine is often caused by a urinary tract infection. Many times you will also notice the urine is cloudy or turbid. Other reasons for reddish urine include feline lower urinary tract disorder, cystitis, bleeding or clotting diseases, trauma and cancer.
Temperature Effects Like most chemical reactions, the rate of an enzyme-catalyzed reaction increases as the temperature is raised. A ten degree Centigrade rise in temperature will increase the activity of most enzymes by 50 to 100%.Variations in reaction temperature as small as 1 or 2 degrees may introduce changes of 10 to 20% in the results.In the case of enzymatic reactions, this is complicated by the fact that many enzymes are adversely affected by high temperatures.ariations in reaction temperature as small as 1 or 2 degrees may introduce changes of 10 to 20% in the results. In the case of enzymatic reactions, this is complicated by the fact that many enzymes are adversely affected by high temperatures.
The pH optimum of an enzyme may be very different from the normal plasma or intracellular average pH of 7.35 - 7.45; some enzymes have pH optima as low as 2 - 3, or as high as 9 - 10, and therefore little or no activity around pH 7.his graph shows the pH dependence of an enzyme that has maximum activity at pH 7.1 (i.e. an optimum pH of 7.1), and a relatively broad range of pH around that optimum at which it has activity. There would still be measurable activity at pH 6 or pH 8.
