In which processes do the enzymes succinate dehydrogenase and cytochrome oxidase occur,respectively?

The Pentose Phosphate Pathway,an alternative pathway of respiration,was elucidated by:

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.

The hexose monophosphate shunt is also called

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

Select the correct option regarding the following statements:
$(1)$ During glycolysis/fermentation,$2 \, ATP$ molecules are produced from one molecule of glucose.
$(2)$ If the respiratory substrate is fat/carbohydrate,the $RQ$ of the respiring cells is less than one.
