Effect of temperature and pH on enzymes
Biology · Secondary 3 · Hard · Effect of temperature and pH on enzymes
An enzyme-controlled reaction is carried out at its optimum temperature. The substrate concentration is then doubled while the enzyme concentration is kept constant. What will most likely happen to the rate of reaction immediately after the change?
- The rate decreases because enzymes are denatured.
- The rate stays the same because temperature is unchanged.
- The rate increases because more substrate molecules collide with enzymes.
- The rate becomes zero because active sites are blocked.
