No, we cannot say that because most enzymes are not at optimal conditions in nature.

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.
Optimum pH level for enzymes?
It depends of the enzyme. For instance. Amylase in the mouth has a higher pH than say pepsin in the stomach.
How are enzymes affected by changes in pH?
A change in pH or and change in temperature will change the shape of the enzyme because its proteins are denatured. Therefore, the enzyme can no longer perform its desired functions because its specific shape has been altered.
How does temperature affect catalase activity?
Increased temp give increased reaction rate. Only an approximation, but 10 degrees is said to double the rate.
What is the temperature that promotes enzymatic action?
Different enzymes are most efficient at different temperatures, these are called 'the optimum temperature'. A temperature far lower than this will cause the rate of reaction to slow until barely noticable. A temperatuere far higher than this will cause the shape of the enzyme to change and the enzyme will become denatured.
How are enzymes influenced by temperature increases or decreases?
For temperatures lower than its optimum, enzymes become inactive. This can be undone by bringing them back to optimum temperature. For temperatures higher than their optimum they are denatured and can no longer function even at optimum temperature.

Are enzymes more stable than most protein molecules found in the cell?
No- most enzymes are only stable within a certain pH, temperature, or chemical environment and will dentaure if the conditions are not right.
Optimum pH level for enzymes?
It depends of the enzyme. For instance. Amylase in the mouth has a higher pH than say pepsin in the stomach.
How might stomach enzymes differ from other enzymes?
Stomach enzymes would have a considerably lower optimum pH than most other enzymes found in the human body.
At what temperature does saliva work the fastest?
The enzymes in the saliva works fastest at optimum temperature (Body temperature) around 37 degrees Celsius. Actually, that's not completely accurate. The higher the temperature, the faster the rate of any chemical reaction, and that's also true of the enzymes in the human body. Our body temperature is regulated right around 37 degrees centigrade (98.6 F), but your body temp can increase, and it does during hard exercise or when you're feverish. At those higher temperatures the enzymes will work more rapidly than they do at 37 degrees. Now, why should that be the case? Why not operate always at optimum temperature? Because as temperature increases, we eventually arrive at a point at which the enzymes begin to denature and stop working. When that happens, the individual dies, which is not a good thing. That's why your body's normal operating temperature is not the optimum temperature for your enzymes. If your body temperature was regulated at optimum temperature under relaxed conditions, when you began to exercise or when you got a fever, your enzymes would denature and you'd die. Regulating your body's temperature at a point 4 or 5 degrees below optimum represents an important safety factor.
Why the maintenance of constant internal environment is important for optimal metabolic efficiency?
The internal environment for cells can never be controlled completely, but the coordinating systems work to maintain a balance within certain limits. This is known ashomeostasis.enzymes control all the metabolic processes in the bodyenzymes work optimally in an environment where their optimum temperature and pH conditions are met.At temperatures and pH values other than the optimum, the enzymes fail to work as efficiently as they should or not at all
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.
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 are enzymes affected by changes in pH?
A change in pH or and change in temperature will change the shape of the enzyme because its proteins are denatured. Therefore, the enzyme can no longer perform its desired functions because its specific shape has been altered.
How to determining the optimum RAM Speed for a given CPU Is there a formula for Determining optimum RAM speed for a given CPU?
Max it out!!! The CPU can only be as fast as it's cache size and than it's memory.
Advantages of thermophilic enzymes than mesophilic enzymes?
Thermophilic enzymes are stable (they grow and thrive) at temperatures between 60-80 degrees Celsius. This makes them easier to study. This is because mesophilic enzymes will denature at these temperatures, and unlike mesophilic enzymes, thermophilic enzymes will not denature at room temp (25 degrees Celsius, making it easier for scientist to work with thermophilic enzymes. In other words, in biotechnology thermoenzymes have thermo stablity that mesophilic enzymes do not, making them much better use under certain conditions ( where mesophilic enzymes would denature).
