$(i)$ 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.

$(iv)$ In both lactic acid and alcohol fermentation not much energy is released; more than seven percent of the energy in glucose is released and not all of it is trapped as high energy bonds of $ATP.$

$(v)$ For aerobic respiration to take place within the mitochondria, the final product of glycolysis pyruvate is transported from the cytoplasm into the mitochondria.
