In which organelle does cellular respiration occur?

The correct answer is D. Mitochondria.

Mitochondria are organelles found in eukaryotic cells that are responsible for energy production. They are often called the “powerhouses of the cell” because they produce adenosine triphosphate (ATP), the cell’s main source of energy.

Chloroplasts are organelles found in plant cells that are responsible for photosynthesis. They use sunlight to convert carbon dioxide and water into glucose and oxygen.

ATP and NADPH are molecules that are produced during photosynthesis and used in cellular respiration.

Cytoplasm is the jelly-like substance that fills the cell and contains all of the cell’s organelles.
