Most human enzymes work best at around what temperature?
|
150 degree Fahrenheit
|
|
98 degree Fahrenheit
|
|
32 degree Fahrenheit
|
|
None of the above
|
Explanation:
Detailed explanation-1: -The optimum temperature for most enzymes is about 98.6 degrees Fahrenheit (37 degrees Celsius).
Detailed explanation-2: -Enzymes are biological catalysts which accelerate chemical reactions in organisms. Optimum temperature is the temperature at which enzyme activity is maximum. In humans, this temperature is 37.5oC that is same as the normal body temperature.
Detailed explanation-3: -High heat destroys enzymes. Enzymes are protein molecules that get denatured at high temperatures. High heat breaks hydrogen and ionic bonds leading to disruption in enzyme shape. The enzyme loses its activity and can no longer bind to the substrate.
