Why would different enzymes have different temperature ranges with different optimal temperatures?

Well, it depends on where in the body the enzyme is located. however, all enzymes in the human body work within a very narrow temperature scale, they don't all have the exact same optimal temp, but they are close. for instance, enzymes in the scrotum have to be able to work at a temp three degrees or so lower than the average human body temperature.

Why does the freezer in the refrigerators goes off and on?
Beause it needs to maintain the temperature selected. It goes on to cool the air, then it turns off when it is at the optimal temperature. When the air warms up again, it turns back on
Can enzymes function at any pH?
No. They function best at the pH corresponding to their usual/intended environment. For example, pepsin, present in the stomach, which is highly acidic, functions best at acidic pH, while trypsin, secreted into the duodenum together with basic bicarbonate, functions best at moderately basic pH. This is true also within subcellular compartments: the optimal pH of lysosomal enzymes is acidic, matching the acidic proteolytic environment inside the lysosome. That said, most enzymes present in the cytosol (~neutral) and blood (~neutral) function best around neutral pH.
What is the scientific study of optimal human functioning?
positive psychology
Do substrates get consumed in enzyme reactions?
On active sites of enzymes, substrates bind to form products.Specific activity is usually expressed as μmol of substrate transformed to product per minute per milligram of enzyme under optimal conditions of measurement.The rate of a reaction is the concentration of substrate disappearing (or product produced) per unit time (mol-1 L-1 s-1 ).
Why is the optimum temperature for E. coli 37 degrees celsius?
Escherichia coli or E. coli is an anaerobic bacterium that lives in the intestines of some organisms. It has an optimum temperature of 37 degree Celsius, which allows it to replicate and grow.
Enzymes have optimal temperatures.most human enzymes have an optimal temperature of about?
The optimal temperature of enzymes in humans is about 37c, the same as the human body's temperature. However, some enzymes work at higher temperatures than 37 but not very high because higher temperatures denatures (destroy) the enzymes.
Do Temperature of the cytoplasm influence the action of enzymes?
Yes, enzymes have optimal working temperatures that differ from enzyme to enzyme
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.
Why all digestive enzymes have their optimal temperature at around 37C?
Digestive enzymes are optimal around 37C due to the temperature allowing for maximum metabolism. The enzymes are most efficient at their highest metabolism and activity.
Why are some bacteria metabolically active in hot springs?
Their enzymes have high optimal temperatures.
Enzymes work most effectively at?
Enzymes work most effectively when they are at their optimal temperature and pH.
Some bacteria are metabolically active in hot springs because?
their enzymes have high optimal temperatures.
How does temperature affect the rate of fermentation?
Alcoholic fermentation involves the actions of enzymes. Enzymes function properly within their optimal temperature range. An increase or decrease in temperature can denature the enzymes, causing them not to function.
Why did the enzyme activity differ at 0c and 100c?
I will assume that you are talking about enzymes found in the normal human body. Enzymes function best at an optimal temperature (in our case, around 37 degrees celsius) because of the inherent tradeoff between reaction rates and protein stability. Remembering your elementary kinetics, the rate of an endothermic reaction (i.e. one that needs energy to function) is directly proportional to the temperature. Since by all means enzymes are biological catalysts, they follow this rule of thumb. However, remembering your biochemistry, higher temperatures lead to protein denaturization, wherein the activity of the enzyme becomes zero due to changes in the protein folding. Thus, in the case of human enzymes, we can expect to see optimal activity at body temp, low activity at lower temperatures, and no activity at very high temperatures.It is important to note though that different enzymes have different optimal temperatures. For example, the DNA polymerase enzyme of Thermophilus aquaticus, a type of bacteria living near volcanic vents has an optimal temperature of around 70-80 degrees celsius!== == the enzymes react faster when the temp. is lower b/c the enzyme would get used to the reaction to keep going and the normal body temp. is closer than 100 degrees celcius>>>......
What is the optimal point mean?
In biochemical reaction, an optimal point is the highest point that the temperature and reach in a reaction without causing damages to the enzymes.
Is temperature a factor that affects enzyme activity?
yes. at low temperature enzymes won't work as effectively, and at high temperature enzymes are denatured.
Enzymes are usually inactivated at what temperature?
The optimal range for the enzymatic activity goes from 25oC to 32oC.
