Which of the following pairs is correctly matched?

  1. Mitochondria – Production of ATP

  2. Golgi body – Synthesis of protein

  3. Lysosome – Synthesis of fats and lipids

  4. Ribosomes – Destruction of foreign substances


Correct Option: A
Explanation:

Mitochondria – Production of ATP Mitochondria are the energy factories of the cells. The energy currency for the work that animals must do is the energy-rich molecule adenosine triphosphate (ATP). ATP is produced in the mitochondria using energy stored in food.
