It means the highest (and best) temperature an enzyme can work until it gets denatured (active site is re-shaped therefore substrate is unable to fit into it anymore).
Hope it helped :)

∙ 14y agothere is a certain temperature that a given enzyme functions best at. below the temperature It doesn't it's rate of activity is lower and above that temperature the enzyme begins to denature and break apart.

∙ 14y agooptimum = the peak of which an enzyme works at its best
taking temperature for example.
if you have the same enzyme under different temperatures you will notice that the rate differs.
if this dosent help let me know :)

What happens to an enzyme if the temperature varies too far from the enzymes optimum temperature?
They do not work as they effectively change shape and so cannot perform their allocated task
How can an enzyme be denatured and why does that process result in the loss of activity of the enzyme?
by increasing the temperature above the optimum temperature(above 45), we can denature an enzyme!! the temperature affects the non-covalent bonds of an enzyme!! at 40
What is the optimum temperature for enzyme activity in the body?
37.5 degree Celsius
What happens to the enzyme when it is cooled below its best working temperature?
When an enzyme coola below a temperature where it can work, it denatures (dies).
Optimum temperature of proteins?
The optimum temperatre like the optimum pH is the temperature at which the protein funcions most effectively. At too low a temperature the reaction kinetics do not allow for a fast reaction and at too high a temperature the enzyme changes it shape and so no longer accepts the substrate so easily. It is often assumed that proteins have and optimum temperature of 37 degrees C as this is the core body temperature of a human being. But this is only for the majority of proteins as many have a much higher or lower optimum temperature.

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.
What is the optimum temperature for enzyme 2?
55 CThis enzyme works best at a temperature of 50 C and a pH of 12.If the enzyme will be above this temperature, it will denature.

How can you destrpy an enzyme?
the way of destroying an enzyme is by increasing the temperature or by making it go over the optimum temperature this destroys or denaturates the leaf.Hope I helped!!!!
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 denaturing enzyme?
enzymes are proteins. when you denature a enzyme you destroy the protein structure/shape. it happens a couple of ways; 1) temperature (they have a 'optimum temperature') at certain temperatures enzymes are denatured 2) Ph, again, they have a 'optimum pH at which they work best, and certain pH levels where they are denatured. 3) Various chemicals..
How may enzymes be deactivated?
high temperature may denature enzyme activity by passing optimum temperature
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.
What happens if enzymes are not at optimum ph?
Enzyme become denatured.
What is the optimum temperature for enzyme activity in the body?
37.5 degree Celsius
What are the effects temperature and pH level have in the efficacy of digestive enzymes?
As you increase the temperature at first the activity of an enzymes will also increase, so the reaction will go faster. At a certain temperature, called the optimum temperature, the enzyme will work at its maximum rate. Above the optimum temperature the enzyme activity decreases. This is due to the loss of shape by the enzyme molecules, a process called denaturation. In mammals, most enzyme shave an optimum temperature of about 37 oC. Roughly speaking, the rate of an enzyme reaction doubles for each 10 oC rise in temperature, until the optimum temperature is reached. pH affects enzymes in a similar way. At a low pH many enzymes have a low activity. As the pH increases the enzyme activity increases until the optimum pH at which the enzyme has maximum activity. Above this pH enzyme activity decreases. These effects are also dueto denaturation of the enzyme molecules at extreme pH values. Many enzymes work best at around pH 7.0. An important exception is pepsin, a protein-digesting (protease) enzyme in the stomach. This works at low pH values such as those found in the stomach (around pH 2.0), due to the presence of hydrochloric acid.
