What is the optimum temperature of enzymes of thermophilic bacteria?
55 to 65 degree Celsius
At which temperature do most enzymes from the human body become completely denature?
i did an experiment in school on enzymes in plants and the optimum temperature for enzymes in a plant it seemed to be at around 40 degrees Celsius so anything above 40 the enzymes denature, but you might have to take into account what fruit it is / where it came from - if its a tropical fruit it might have a higher optimum temperature because of the climate it came from- that's just an idea
At what temperature does saliva work the fastest?
The enzymes in the saliva works fastest at optimum temperature (Body temperature) around 37 degrees Celsius. Actually, that's not completely accurate. The higher the temperature, the faster the rate of any chemical reaction, and that's also true of the enzymes in the human body. Our body temperature is regulated right around 37 degrees centigrade (98.6 F), but your body temp can increase, and it does during hard exercise or when you're feverish. At those higher temperatures the enzymes will work more rapidly than they do at 37 degrees. Now, why should that be the case? Why not operate always at optimum temperature? Because as temperature increases, we eventually arrive at a point at which the enzymes begin to denature and stop working. When that happens, the individual dies, which is not a good thing. That's why your body's normal operating temperature is not the optimum temperature for your enzymes. If your body temperature was regulated at optimum temperature under relaxed conditions, when you began to exercise or when you got a fever, your enzymes would denature and you'd die. Regulating your body's temperature at a point 4 or 5 degrees below optimum represents an important safety factor.
How are conditions made suitable for enzymes?
Optimum temperature and pH medium make suitable conditions for enzymatic reactions.
What affect does temperature have on cellular enzyme activity?
Enzymes generally work within a given temperature range. As the temperature is increased the activity will increase. However if the optimum temperature is surpassed, the enzymes will stop working.
How are enzymes influenced by temperature increases or decreases?
For temperatures lower than its optimum, enzymes become inactive. This can be undone by bringing them back to optimum temperature. For temperatures higher than their optimum they are denatured and can no longer function even at optimum temperature.
Optimum temperature of polyphenoloxidase?
The optimum temperature for the enzyme polyphenol oxidase (PPO) is 40 degrees Celsius. This is the temperature at which the enzyme is most effective; like many other enzymes the rate of reaction will decrease with temperature, but if the temperature rises much above the optimum level, it will cause the enzymes to denature. Denatured enzymes will stay denatured even if the temperature decreases again. The optimum pH for polyphenol oxidase is 5.
What is the optimum temperature of enzymes of thermophilic bacteria?
55 to 65 degree Celsius
What can a fever slow down?
enzymes best function at optimum temperature for human body optimum temperature is 37 C, raise in optimum temperature affects the function of enzymes and with very high temperature enzyme activity ceases. high temperature also affects proteins resulting in protein structural changes. fever slow down the enzyme activity.
How may enzymes be deactivated?
high temperature may denature enzyme activity by passing optimum temperature
At what temperature do human enzymes work best at?
Enzymes in the human body work best at human body temperature, so about 35-40 degrees (Celsius). A lower temperature would have too low of an effect to be able to sustain life, and a higher temperature causes the enzyme to denature (unravel) and be rendered ineffective.
What are three optimum procedures which increase the relative rate of an enzymes performance?
Temperature, pH and time

How are conditions made suitable for enzymes?
Optimum temperature and pH medium make suitable conditions for enzymatic reactions.
What are the optimum temperature and the optimum pH of an enzyme?
Every enzyme works at its maximum rate at a specific temprature called as optimum temprature for that enzyme. AND all enzymes work at their maximum rate at narrow range of pH, called as optimum pH. A slight increase or decrease in pH causes the retardation in enzyme activity or blocks it completely.
How does temperature affects activity?
The enzyme activity increases as the temperature rises due to the substrates colliding with the enzymes' active sites more frequently at higher temperatures. However, each enzyme has an optimum temperature as high temperatures denature enzymes.
