Question

10 where does cellular respiration take place? a mitochondrion b nucleus c chloroplast d ribosome

Explanation:

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water. Mitochondria are known as the "powerhouses" of the cell because they are the site where most of cellular respiration (specifically the Krebs cycle and oxidative phosphorylation) occurs. The nucleus contains the cell's genetic material. Chloroplasts are involved in photosynthesis (in plant cells). Ribosomes are involved in protein synthesis.

Answer:

A. mitochondrion
