What happens to muscle cells during cellular respiration?

During cellular respiration, muscle cells convert glucose and oxygen into adenosine triphosphate (ATP), the energy currency of the cell. This process occurs in the mitochondria and involves glycolysis, the Krebs cycle, and the electron transport chain. As ATP is produced, carbon dioxide and water are released as byproducts. In the absence of sufficient oxygen, muscle cells can also undergo anaerobic respiration, leading to the production of lactic acid.
