What is the optimal temperature for potato catalase?
around 35.3°C
What are the optimal conditions for catalase?
Catalase Background Information It is a tetramer of four polypeptides chains containing four porphyrin heme groups that allow the enzyme to react with the hydrogen peroxide. The optimum PH of human catalase is approximately 7 and the optimum temperature is at 37 degree.
Why did catalase not function well at 80 C?
The catalase failed to function at 80°C because it had surpassed its optimal functioning temperature to the point of damaging the enzyme. The enzyme function increased before it was saturated with substrate because it hadn’t yet had enough substrate to saturate all the enzymes.
What happens to catalase activity at 80 C?
During finding the optimum temperature , the enzyme showed high activity at 80C, for 10 minutes incubation, but when the optimum temperature i.e. 80c was used for its thermal stability, then we find that the enzyme showed abrupt decline in its activity and will show some activity after 10 minutes incubation , 20 …
Why did the catalase no longer function?
Why did the catalase function level off when different hydrogen peroxide concentrations were tested? At some point, all the catalase in solution was catalyzing reactions, so even if the hydrogen peroxide concentration was increased, the rate of the reaction could not increase any more.
What effect did temperature have on oxygen production?
What effect did temperature have on oxygen production? Oxygen production increased from 10 to 30 °C but decreased from 30 to 40 °C. If the bath was set to 80 °C, what do you think would happen to the rate of photosynthesis? It would decrease because the temperature would be high enough to damage the plant.
Which temperature generated the greatest oxygen production?
30 °C
How does temperature affect oxygen production hypothesis?
Because oxygen is a product of the light reactions of photosynthesis, our results show that increasing the temperature increases the rate of photophosphorylation. A possible explanation for this is that increasing temperature increases the kinetic energy of a system (Petrucci et al. 2011).
