In the presence of a dilute salt solution,the rate of respiration in a respiring tissue:

It is much easier for a small animal to run uphill than for a large animal,because

Select the correct match for $X$ and $Y$:

Column $X$	Column $Y$
$(1)$ Mitochondrial matrix	$(P)$ Photophosphorylation
$(2)$ Chloroplast stroma	$(Q)$ Oxidative phosphorylation
$(3)$ Cristae	$(R)$ Krebs cycle
$(4)$ Granum	$(S)$ Dark reaction

During respiration,substrate level phosphorylation occurs in . . . . . . .

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

Match the processes involved in aerobic respiration given in Column-$I$ with their occurrence in the cell from Column-$II$ and choose the correct option.

Column-$I$	Column-$II$
$i$. Glycolysis	$b$. Cytoplasm
$ii$. Krebs cycle	$a$. Mitochondrial matrix
$iii$. $ETS$	$c$. Inner mitochondrial membrane
