Question

Explain the following terms giving one example of each type:
(i) Antacids,
(ii) Disinfectants,
(iii) Enzymes.

Answer 1

I) Antacids are medicines that neutralize stomach acid, e.g. brioschi $NaHC{O}_3$.

II) Disinfectants are chemicals used to kill micro-organism, applied only to non-living objects like floors and drains, e.g. 1% phenol solution.

III) They can break down large, energy-rich molecules in many steps to extract chemical energy in small portions to drive their many activities. Most of these reactions are catalyzed by biochemical catalyst calle enzymes. Enzymes are proteins with high molar mass ranging from 15,000 to 1,000,000 g/mol. Enzymes are incredibly efficient catalysts.
