Question

Write short notes on

(a) Mitochondria.

Answer 1

• The mitochondria are the semi-autonomous organelles that produce their own proteins and are present in the cytoplasm of the cell.
• Mitochondria are sites of cellular respiration which use oxygen from the air to oxidize the carbohydrates and fats (lipids) present in the cell to carbon dioxide and water.
• This process of cellular respiration releases energy in the form of ATP (adenosine triphosphate) which is used in the metabolic activities of the cell.
