All life relies on a relatively narrow range of pH, or acidity, and biochemical reactions are catalyzed by enzymes that have very narrow ranges of optimum pH values. Given these facts, all what relies on a narrow range where biochemical reactions can be catalyze by enzymes among the following options:
- sugar
 - weathering
 - Crops
 - CO 2
 - climate
 - heat
 - life
 - weather
