Solution

Rice, potatoes, and bread are sources of carbs. During digestion, these carbs are broken down into simpler compounds known as glucose. This glucose interacts with oxygen in our cells to generate energy. This reaction is specifically termed respiration. Thus, respiration is an exothermic process, as energy is generated throughout it.

\[\ce{C6H12O6_{(aq)} + 6O2_{(aq)} -> 6CO2_{(aq)} + 6H2O_{(l)} + energy}\]
