The three boxes in this diagram represent the three major biosynthetic pathways in aerobic respiration. Arrows represent net reactants or products. Arrows numbered $4, 8$ and $12$ can all be

The main purpose of glycolysis,the Krebs cycle,and the electron transport system is the production of .........

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.

Decarboxylation is not involved in

Distinguish between the following: (Any two)
$(a)$ Aerobic respiration and Anaerobic respiration
$(b)$ Glycolysis and Fermentation
$(c)$ Glycolysis and Citric acid Cycle

Match the location of the cell given in Column $I$ with its function in Column $II$.

Column $I$	Column $II$
$A$. Mitochondrial matrix	$i$. Krebs' cycle
$B$. Cytoplasm	$ii$. $ETC$
$C$. $F_0$ and $F_1$	$iii$. Glycolysis
$D$. Inner Mitochondrial membrane	$iv$. $ATP$ synthesis
