Anaerobic respiration benefits human survival primarily by exercise.
Cellular respiration is the reaction which human body cells can employ to produce energy needed for them to stay alive and function.
Rhe broken down of glucose by cells generates energy which uses oxygen-dependent in anaerobic respiration where it does not require oxygen. Anaerobic respiration helps in exercise for human survival. It occurs in cells when in high-intensity exercise. It also occurs with activities that require intense bursts of muscle power, for example, powerlifting and sprinting.
Anaerobic generates energy faster and its' fast-twitch enables muscle fibres to relatively quick fatigue.
