Enzymes are sensitive to temperature enzyme has its optimum temperature for its maximum activity,above and below this temperature its rate of reaction decreases.Most of enzymes are highly active at about 37C and are completely destroyed at 100C,whereas at minimum i.e.0C, activity is reduced to minimum but enzymes are not destroyed.
It depends on the type of enzyme and where that enzyme is located. For example, an average enzyme in the human body prefers 98.6 degrees F plus or minus a few degrees depending on where the enzyme is in the body.
It is interesting to note that a high fever is fatal to the human body because the temperature of the body gets too high and the enzyme begins to unravel. Therefore their function stops and, without that function, the human body will begin to shut down leading to possible death.
Other enzymes function in completely different temperatures. For example, extremophiles are organisms that live in extreme conditions (hence the name) ranging from about 0 degrees Fahrenheit to upwards of about 180 degrees F. Obviously they need their enzymes to function at these temperatures extreme temperatures and therefore these temperatures are their optimum temperature.
The temperature at which the enzyme works best.
Generally speaking, reactions tend to proceed more quickly as the temperature increases. However, enzymes are biological molecules (specifically proteins), which tend to become denatured at elevated temperatures. The optimum temperature for any given enzyme is a compromise between these two competing factors, and varies depending on exactly what the enzyme is.
It depends on what organism it is in. For humans, the optimum temperature is around 38 degrees Celsius.
It generally depends, but the general optimum temperature is around 37 degrees, your bodies internal homeostasis.
if you mean optimum temperature, it is 37 degrees Celsius for enzymes inside our body, so i suppose most enzymes have an optimum temperature of about 37-40 degrees Celsius
This is difficult to answer based solely on the information in your question. The optimal temperature for a specific enzyme cannot be determined without knowing what the enzyme is.
50°C
25- 40 c
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.
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.
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..
The three main factors that affect enjyme activity are:- a)Temperature:Enzymes generally function properly at a narrow rangr of temperature and shows its highest activity t a particular temperature called its optimum temperature. b)pH:-as temperature pH also has a particular value ,in which the enzymes are most active,called the optimum temperature. c)Concentration of substrate;-with the increase in substrate concentration,the velocity of the enzymatic reaction also increases,till a maximum velocitywhich does not rise any further with the rise in substrate concentration.
Enzymes have different optimum pH levels. Trypsin, which is found in the intestines has an optimum pH of 8-9. Higher or lower than that, its activity decreases until it reaches to a level where the H-bonds holding the protein structure is destroyed. A loss of structure means a loss of function, therefore the enzyme has been denatured. Pepsin on the other hand operates at a more acidic pH, typically 1.5-2. The enzyme, salivary amylase has an optimum pH of 7. In the body, the optimum pH of enzymes vary, the optimum temperature however is close to body temperature, which is 37C or 98.6F. Extreme heat denatures the enzyme, cold on the other hand, only INHIBITS it.

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
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!!!!
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.
high temperature may denature enzyme activity by passing optimum temperature
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.
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 :)
They do not work as they effectively change shape and so cannot perform their allocated task
37.5 degree Celsius
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.
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.
