Steps of respiration are controlled by

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

What are the main steps in aerobic respiration? Where does it take place?

Pyruvic acid is the end product of glycolysis. What are the three metabolic fates of pyruvic acid under aerobic and anaerobic conditions? Write them in the space provided in the diagram.

Read the following statements and choose the set of correct statements :
$(A)$ In fermentation,the reducing agent is $NADH + H^+$.
$(B)$ There are three major ways in which different cells handle pyruvic acid produced by glycolysis.
$(C)$ The complete oxidation of pyruvate occurs by the stepwise removal of all the hydrogen atoms,leaving two molecules of $CO_2$.
$(D)$ The $NADH$ synthesised in glycolysis is transferred into the mitochondria and undergoes oxidative phosphorylation.
$(E)$ Complex-$IV$ of $ETS$ refers to cytochrome $c$ oxidase complex.
Choose the most appropriate answer from the options given below :

The lactic acid generated during muscle contraction is converted to glycogen in
