In fact, on an average day, an average human being will use up to 50 to 75kg of ATP, with each ATP recycled (ATP to ADP and back to ATP again) 500 to 750 times. That is roughly our bodyweight, or around 6 × 1025 – 9 × 1025 (a ‘6’ or ‘9’ followed by twenty-five zeroes) molecules of ATP every single day in order to keep everything in our body ship-shape and ticking along.
