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.

∙ 9y agoOne of the two conditions that need to be just right in order for enzymes to work best is they must be at body temperature. The other condition that must be met is that the PH must be neutral.

∙ 11y agoEach type of enzyme have it is own specific optimum condition under which it works.
Enzyme in human body work best at body temperature and neutral pH condition, except Pepsin which work at very low pH.

∙ 13y agoIt is very specific to the enzyme. Enzymes living inside cells have completely different conditions to those living outside the cells.
That's why our body has the E.R(Endoplasmic Reticulum). It uses the E.R to have a controlled environment for proteins(enzymes) leaving the cell, that need specific conditions different than those inside the cell.
In general all enzymes die below a pH of 5 or above a pH of 9.
Optimum temperature ranges around body temperature, which stands near 37 degrees Centigrade.

Can we say that enzymes work in optimum conditions only if yes than why?
No, we cannot say that because most enzymes are not at optimal conditions in nature.
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>>>......
How does salt affect enzymes?
Salt concentration affects all enzymes differently. Depending on the situation, salt concentration has the ability to precipitate or unfold the enzyme. It also has the ability to disrupt hydrogen binding and binding to ionic residues decreasing, which could increase the activity of the enzyme.
How do pH temperature and substrate availability affect the rate of action of enzymes?
All enzymes have optimal conditons, when it will work at its best. For example, if the temprature is too high the protein can become denatured. This is alos the case with Ph. Substrate level also affects enzyma activity because the more substartes there are, the more enxymes can bind to them.
Why does the stomach contain HCl?
HCl lowers the pH in the stomach and provides the acidic conditions for the digestive enzymes in the stomach to work effectively.
Can we say that enzymes work in optimum conditions only if yes than why?
No, we cannot say that because most enzymes are not at optimal conditions in nature.
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.
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.
Enzymes work most effectively at?
Enzymes work most effectively when they are at their optimal temperature and pH.
Do Temperature of the cytoplasm influence the action of enzymes?
Yes, enzymes have optimal working temperatures that differ from enzyme to enzyme
What is the optimal point mean?
The optimal point in statistics refers to the point where a function reaches its maximum or minimum value. In the context of a probability distribution, the optimal point would typically refer to the mean or expected value of the distribution. This point represents the average value of the data and is often used as a measure of central tendency.
Which conditions do enzymes work best at?
Each enzyme will be different. They each have their own optimum pH, and temperature. Some require certain other ingredients for optimal activity, such as a particular ion, or maybe a cofactor.
Why are some bacteria metabolically active in hot springs?
Their enzymes have high optimal temperatures.
What are the conditions for the optimal function of a cell?
it nust be rechargable.
What types of conditions affect enzymes?
if the envirionment is cold, the reaction rate decreases. if the envirionment is warm, the reaction rate increases. however, if the envirinment is too hot, the enzyme will be denatured. a pH out of the enzyme's optimal range will also denature it. when an enzyme is denatured, it looses its shape a its active site is no longer able to recive the molecule and break it down.
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.
