About this simulation

Balance aerobic inputs and outputs. The model assumes 30 ATP per glucose; real yields vary. Glycolysis and fermentation can still release energy without oxygen.

What students can explore

Set glucose and oxygen to each pair. Record carbon dioxide, water and ATP.
Check the equation C6H12O6 + 6O2 → 6CO2 + 6H2O by counting atoms.

Learning objectives

1Balance aerobic respiration and identify a limiting reactant.

Questions teachers ask

What assumptions does this model use?

Amounts are idealised molar quantities, not a cell-scale concentration or rate. ATP production is coupled to multiple processes; the summary equation omits those steps.

How do I reset the investigation?

Use Reset experiment to restore the starting controls. Use the sliders with a pointer, touch or keyboard. The model runs without an account.
