During how many steps is Co-$A$ used in aerobic respiration?

Select the correct statements from the following:
$I-$ During respiration,plants take in $CO_2$ and release $O_2$.
$II-$ The surface of most cells in plants is in contact with air.
$III-$ The loose arrangement of parenchyma cells in leaves,stems,and roots creates a network of air spaces.
$IV-$ The energy released during respiration is stored in the form of $ATP$.
$V-$ Glucose is oxidized to release energy in only a single step.

Match Column-$I$ with Column-$II$ and select the correct option.

Column-$I$	Column-$II$
$a.$ Cis-aconitate	$i.$ $4 \ C$-compound
$b.$ $\alpha$-ketoglutarate	$ii.$ $3 \ C$-compound
$c.$ Fumarate	$iii.$ $6 \ C$-compound
$d.$ $1,3$-diphosphoglyceric acid	$iv.$ $5 \ C$-compound

$A$: Carbohydrates are the primary source of energy in living organisms.
$R$: Glucose is the common substrate used in respiration.

Choose the correct option:
$(1)$ Sucrose is converted into glucose and fructose with the help of the enzyme $Invertase$ / $Maltase$.
$(2)$ In fermentation,glucose is converted into ethanol by yeast under $Aerobic$ / $Anaerobic$ conditions.

Mention the important series of events of aerobic respiration that occur in the matrix of the mitochondrion as well as one that take place in the inner membrane of the mitochondrion.
