State two similarities between aerobic and anaerobic respiration.

Answer the following:

How are alveoli designed to maximise the exchange of gases?

The above graph shows the amount of CO₂ produced by plant cells at various levels of atmospheric O₂. In respiration at atmospheric oxygen below 1 % level, the CO₂ released is relatively high. This is due to
