(D) The conversion of $Pyruvic$ $acid$ $(3C)$ into $Acetyl-CoA$ $(2C)$ occurs in the mitochondrial matrix. This process is catalyzed by the $Pyruvate$ $dehydrogenase$ complex. During this reaction,one molecule of $CO_2$ is released (decarboxylation) and $NAD^+$ is reduced to $NADH + H^+$ (oxidation). Therefore,this step is known as $Oxidative$ $decarboxylation$.

Match the respiration types with their respective respiratory substrates:

Respiration Type of substrate

$A$. Floating respiration $i$. Proteins

$B$. Cytoplasmic respiration $ii$. Starch

$C$. Protoplasmic respiration $iii$. Carbohydrates

$D$. Lactic acid fermentation $iv$. Lactose

Select the correct matching sequence:

Respiration	Type of substrate
$A$. Floating respiration	$i$. Proteins
$B$. Cytoplasmic respiration	$ii$. Starch
$C$. Protoplasmic respiration	$iii$. Carbohydrates
$D$. Lactic acid fermentation	$iv$. Lactose
