Question

Enzymes generally have
A) Same pH and temperature optima
B) Same pH but different temperature optima
C) Different pH but same temperature optima
D) Different pH and different temperature optima

Answer 1

the correct option is D

Answer 2

Each enzyme has its own unique and a favourable pH value but the same temperature optima.

• Although higher temperatures increase enzyme activity and reaction rate, enzymes tend to be proteins and, as with all proteins, the temperatures above 104 degrees Fahrenheit or 40 degrees Celsius, will begin to break them down.
• A solution's pH may have multiple effects on the enzyme structure and its behaviour. Changes in pH may not only affect an enzyme's shape, but may also alter the substratum's shape or the charging properties so that either the substratum binds to the active site or is unable to undergo any catalysis.
