Question

What is the location within a cell where cellular respiration occurs?

The cell membrane
The chlorophyll
The mitochondrion
The cytoplasm

Answer 1

Cellular respiration primarily occurs in the **mitochondrion**. This organelle is often referred to as the "powerhouse of the cell" because it is responsible for producing ATP (adenosine triphosphate), the energy currency of the cell, through the process of cellular respiration. While some stages of cellular respiration, such as glycolysis, occur in the cytoplasm, the main energy production happens in the mitochondria.
