Differentiate between (Any two):
$(a)$ Respiration and Combustion
$(b)$ Glycolysis and Krebs' cycle
$(c)$ Aerobic respiration and Fermentation

What is the importance of respiration in plants?

The co-factors required for the formation of acetyl $Co-A$ are:

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

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.

$A$: In $PPP$ $(HMS)$,complete oxidation of one glucose molecule would produce $6CO_2$ molecules and $12$ $NADPH_2$ molecules.
$R$: It occurs in cytoplasm and chloroplast,in presence of $O_2$.
