Bonds between the strands are relatively weak hydrogen bonds, whereas bonds within the strands are relatively strong covalent bonds.
<span>This is probably caused by ill-fitting shoes putting pressure on certain areas of the foot and would be called a Corn.

In cellular respiration, glucose is broken down by reacting it with oxygen to produce carbon dioxide and water.
C6H12O6 + 6O2 -> 6CO2 + 6H2O
In fossil fuels, methane or any other fuel is combusted using oxygen.
CH4 + 2O2 -> CO2 + 2H2O
The combustion of glucose happens in cellular respiration.
