How many $ATP$ molecules are produced via substrate-level phosphorylation during the complete oxidation of one glucose molecule in aerobic respiration?

$A$ student has taken a twig from a plant. She/he observes a droplet of fluid exuding from the cut surface of the twig. What is this fluid?

Assertion : Glycolysis is the first step of respiration in which glucose completely breaks into $CO_2$ and $H_2O$.
Reason : In this process,there is net gain of twenty four molecules of $ATP$.

Choose the correct statements:
$(i)$ The complete combustion of glucose,which produces $CO_2$ 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 $2$ steps,not $4$.
$(iv)$ In both lactic acid and alcohol fermentation,not much energy is released; less than $7$ 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.

During a state of rest,the metabolic requirement is very low. This can be determined by:

Differentiate between Glycolysis and Citric acid cycle.
