Question

The cell organelle which helps in oxidation phosphorylation is

• A. Chloroplast
• B. Mitochondria
• C. Ribosome
• D. Endoplasmic reticulum

Answer 1

The correct option is B Mitochondria

• Oxidative phosphorylation is a metabolic pathway in which the cells use enzymes to oxidize nutrients.
• This oxidation of nutrients releases energy which is used to produce adenosine triphosphate (ATP) molecule.
• Mitochondria found in the cytoplasm of all eukaryotic cells is the primary site to generate large quantities of energy in the form of ATP molecules.
  
• Therefore, it is also known as the powerhouse of the cell.

So, the correct answer is 'Mitochondria'.
