Live chart, last 60 seconds. Rates are per second of simulation. Each H⁺ dot in the factory stands for one ATP's worth of pumped H⁺ (a simplification of the real numbers). Time is sped up.
Simplified teaching model. Glucose in mg/dL; insulin and glucagon are relative levels. Meals are marked with a fork. Tap or drag on the chart to jump to a time.
Drag a card onto a box, or tap a card and then tap a box. Tap a placed card to send it back.
Wrong answers are fine here. Read why, then try again.
Simplified teaching model. Heat flows are in watts (rough values). One second here is about one minute of real time. Normal core range shown is 36.5–37.5 °C (OpenStax).
Rough teaching estimate: BMR from lean body mass, times an activity factor, plus about 10% of intake to digest food. Weight change uses the rule of thumb of about 7,700 kcal per kg (3,500 per lb). Real bodies adapt, so long-term changes are smaller.
