Where does cellular respiration occur? (1 point)

lungs
chlorophyll
mitochondria
bacteria

Cellular respiration occurs in mitochondria.

Cellular respiration occurs in the mitochondria.

The correct answer is mitochondria.

To arrive at this answer, let's break down the options:

1. Lungs: The lungs are responsible for respiration in humans and animals. However, cellular respiration occurs within cells, not in the lungs themselves.

2. Chlorophyll: Chlorophyll is a pigment found in plants and is responsible for capturing sunlight during the process of photosynthesis, not cellular respiration.

3. Mitochondria: Cellular respiration occurs in the mitochondria, which are membrane-bound organelles found in eukaryotic cells. Mitochondria are often referred to as the "powerhouses" of the cell because they generate energy (in the form of ATP) through the process of cellular respiration.

4. Bacteria: Bacteria perform cellular respiration, but it occurs within the cytoplasm of the bacterial cell and not within mitochondria. Bacteria don't possess mitochondria since they are prokaryotes.

Therefore, the correct answer is mitochondria.
