The given schematic diagram shows three main biosynthetic pathways of aerobic respiration in three boxes. The arrows indicate reactants or products. Arrows $4, 8,$ and $12$ all represent -

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 :

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

The two waste products of oxidation in cells are

Steps of respiration are controlled by

If a starved plant is provided with glucose,the rate of respiration would
