Question

where does cellular respiration take place?
mitochondria
chloroplast
cytoplasm
nucleus

Explanation:

Cellular respiration is the process by which cells convert nutrients into energy (ATP). Mitochondria are known as the "powerhouses" of the cell because they are the main site for aerobic cellular respiration. Chloroplasts are involved in photosynthesis (not respiration). The cytoplasm is where glycolysis (the first stage of cellular respiration) occurs, but the majority of ATP production (from the Krebs cycle and electron - transport chain) happens in mitochondria. The nucleus is mainly for storing genetic material and not the site of respiration.

Answer:

A. Mitochondria
