Question

1. besides temperature and concentration, what is the third major factor that affects enzyme activity? describe what happens when this factor is outside the optimal range.

Explanation:

Enzyme activity is also affected by pH. When pH is outside the optimal range, the enzyme's structure can be altered, leading to reduced activity or denaturation.

Answer:

The third major factor is pH. When pH is outside the optimal range, enzyme - structure can be disrupted and its activity decreases or it may denature.
