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.
How does temperature effect enzyme action?
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.
What is the optimum temperature for pepsin activity in Celsius?
According to Biologists, the optimum temperature for pepsin ranges from 37 degrees Celsius to 42 degrees Celsius which are perfect human body temperatures.
What condition is best for enzyme activity?
enzymes work best at body temperature, that is if the enzmes are human.
What happens to the enzyme below 30 degrees?
Enzymes work best at around body temperature. It the temperature is too cold then the enzyme activity slows down to almost zero. The activity of the enzyme steadily increases to a temperature of around 50 to 55 oC depending on the enzyme. After that temperature the enzyme is denatured and ceases to function. At 45 oC the enzyme is most likely still functioning but is close to the temperature where it will be destroyed.
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 is the optimum temperature of an enzyme?
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.
What two internal body conditions effect enzyme activity?
temperature and pH
How else might the energy released be used in mammals and in birds?
For keeping there body at optimum temperature for caring out enzyme reactions

Does PH change the shape of the active site of an enzyme?
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.

How temperature and pH affect enzyme activity?
Temperature And Enzyme Activity: Increasing temperature means the molecules gain more kinetic energy and move faster resulting in more chances of successful collisions of enzymes and substrates forming enzyme-substrate molecules.
Why it is recommended on biological washing powders to wash clothes at low temperature?
Far as I concern, the claim on low temperature is not accurate. Usually what branded a biological washing powder is inclusion of enzyme to help remove grease and protein. Higher temperature give more kinetic energy and so the enzyme activity increase. However, when the temperature is too high the enzyme may denature. For the Lipase enzyme, optimum temperature is 37 C. I don't think 37 C is considered low temperature. It is rather stated best use at human body temperature.
What condition is best for enzyme activity?
enzymes work best at body temperature, that is if the enzmes are human.
What are optimal conditions of enzymes?
every enzyme has specific optimum temperatures and pH. 1. The pH is very specific even a minor change of .5 will cause the enzyme to denature. 2. The temperature is less specific all enzymes will work below the optimum temperature but the reaction will be slower. Above the optimum temperature the enzyme will denature. Note the optimum temperature of the human body is around 37.5 degrees C and the optimum pH is around 7.3.
