Give two functions of mitochondria.

Ans. The two functions of mitochondria are:

• Energy production – The citric acid cycle, often known as the Krebs cycle, is responsible for the majority of ATP production in mitochondria. Mitochondria are organelles that transfer chemical energy from the food we eat into a condition that the cell could use. This is known as oxidative phosphorylation.
• Dead cell removal – Apoptosis, or cell death, is an inevitable aspect of life. Cells are cleaned away and destroyed as they get old or broken. Mitochondria decide which cells are killed. Mitochondria produce cytochrome C, which triggers caspase, one of the most important enzymes involved in apoptotic cell death.

Mitochondria are assumed to have a role in disease because certain disorders, such as cancer, include a breakdown in regular apoptosis.
