Question

Which cell organelle contains enzymes for ATP production?

Answer 1

Hint: ATP is the energy currency of the human body and it is produced with the help of special enzymes which are produced in the “Powerhouse of the cell”. It is also involved in the protein production due to the presence of DNA in this cytoplasmic organelle.

Complete answer:
Cell is the basic functional and structural unit of the organisms. Cells are involved in the production of all proteins, transportation and tagging of the proteins. It includes the organelles like nucleus, ribosomes, Golgi apparatus, Mitochondria, etc.
Mitochondria is the organelle involved in the production of self-protein because of the presence of double stranded DNA which helps in the reproduction of the mitochondria and its survival. It is found in the cytoplasm of the eukaryotic cells and it has a double membrane which is made up of hydrophobic and hydrophilic ends. This membrane is semi-permeable.

Inner membrane is involved in respiration and ATP synthesis. This allows small molecules like water, oxygen and carbon dioxide. Inner membrane has folded structures which are called as cristae and helps in the increasing surface area of membrane required for ATP production.
Electron transport chains, enzymes and proteins required for ATP production are transported to this membrane. A redox reaction is involved in this process and DNA which is present in the mitochondria give directions for the ATP production.
Thus, we can conclude the ATP production and enzyme production required for the ATP synthesis takes place in the mitochondria.

Note: Oxygen is the ultimate electron acceptor in the electron transport chain thus it is very necessary to have sufficient amount of oxygen in the body. Sufficient amount of oxygen leads to aerobic respiration and low levels of oxygen in the body leads to anaerobic respiration.
