which organelle is responsible for cellular respiration

The organelle responsible for cellular respiration is the mitochondrion , often called the “powerhouse of the cell” because it produces most of the cell’s ATP energy.

Which organelle is responsible for cellular respiration?

Quick Scoop

Cellular respiration is the process cells use to break down glucose and other nutrients to make ATP, the usable energy currency of the cell. In almost all eukaryotic cells (plants, animals, fungi, protists), this job is mainly handled by the mitochondria.

• The main organelle for cellular respiration: mitochondrion.

• It carries out key stages such as the Krebs cycle and oxidative phosphorylation.

• That’s why it’s nicknamed the powerhouse of the cell: it generates the bulk of ATP.

In simple classroom or exam questions like “which organelle is responsible for cellular respiration?”, the expected one-word answer is:

Mitochondria.
