Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Every enzyme has a optimal temperature and pH. True or False?
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -In the same way that every enzyme has an optimum temperature, so each enzyme also has an optimum pH at which it works best.

Detailed explanation-2: -Each enzyme has an ideal temperature and pH: pH: Enzymes are sensitive to acidity and alkalinity. They don’t work properly if an environment is too acidic or basic. For example, an enzyme in the stomach called pepsin breaks down proteins.

Detailed explanation-3: -The activity of enzymes is reported to be highest when the pH is between 5 and 7. On the other hand, some enzymes demand a more pronounced pH range of 1.7 to 2. In some circumstances, the pH optimal is determined by the location. The ideal temperature for enzymes is said to be between 20 and 35 degrees Celsius.

Detailed explanation-4: -Every enzyme has an optimum temperature; the temperature at which the enzyme activity is greatest. This can be different from one enzyme to the next, but enzymes within the human body tend to have optimum temperatures around 37°C.

Detailed explanation-5: -In general, an enzyme has an optimum pH. Although most enzymes remain high activity in the pH range between 6 and 8, some specific enzymes work well only in extremely acidic (i.e. pH <5.0) or alkaline (i.e. pH >9.0) conditions.
