How many molecules of $CO_2$ are released during the complete oxidation of one molecule of pyruvic acid?

Given below are some reactions and the enzymes involved. Identify the $CORRECT$ pairs.

Column $I$	Column $II$
$a.$ Fructose $1,6$-diphosphate $\rightarrow$ $3$-$PGAL$ + $DHAP$	$i.$ Enolase
$b.$ Citrate $\rightarrow$ $CIS$-aconitate	$ii.$ Thiokinase
$c.$ Succinyl $CoA$ $\rightarrow$ Succinate	$iii.$ Aconitase
$d.$ $2$-$PGA$ $\rightarrow$ $PEP$	$iv.$ Aldolase

Match the name of the scientist or discovery with its corresponding pathway or process:

$A$. $PPP$ (Pentose Phosphate Pathway)	$i$. Kuhne pathway
$B$. Demonstration of fermentation	$ii$. Kreb's cycle
$C$. $TCA$ cycle	$iii$. Warburg-Dickens pathway
$D$. Glycolysis	$iv$. Embden-Meyerhof-Parnas pathway

Choose the correct matching sequence:

Photosynthesis and respiration are similar because:
$I$. In eukaryotes,both processes occur in specialized organelles.
$II$. $ATP$ synthesis in both is explained by the chemiosmotic theory.
$III$. Both use an $ETC$ (Electron Transport Chain).
Select the correct option.
