Human muscle cells are facultative anaerobes thal perform lactic acld fermentation when oxygen is depleted from muscle tissues, During periods of high physical activity, such as a 100-meter sprint, ATP Is rapidly used for muscle contraction The limited oxygen delvered to muscle cells becomes a problem, and aerobic respiration is blocked. In Anaerobic respiration, the ATP provided by rapid fementation, temporarily provides energy to maintain musde function in the absence of oxygen until oxygen levels are restored. A. Glucose + Oxygen (O 2)
B. Ethanol + Carbon Dioxide (CO 2)
C. Water + Carbon Dioxide (CO 2)
D. Lactic Acid + Oxygen (O 2)
