$(i)$ The complete combustion of glucose, which produces $O_2$ and $H_2O$ as end products, yields energy most of which is given out as heat.
$(ii)$ The scheme of glycolysis was given by Gustav Embden, Otto Meyerhof and J. Parnas and is often referred to as the $EMP$ pathway.
$(iii)$ In glycolysis, $ATP$ is utilised at $4$ steps.
