In the given diagrammatic representation of ATP synthesis in mitochondria, A, B and C are respectively:
  
1. 2 ${\mathrm{H}}^{+}$, ${\mathrm{F}}_0$ and ${\mathrm{F}}_1$
2. 2 ${\mathrm{H}}^{+}$, ${\mathrm{F}}_1$ and ${\mathrm{F}}_0$
3. 4 ${\mathrm{H}}^{+}$, ${\mathrm{F}}_0$ and ${\mathrm{F}}_1$
4. 4 ${\mathrm{H}}^{+}$, ${\mathrm{F}}_1$ and ${\mathrm{F}}_0$

During the process of respiration redox equivalents are removed:

1. In form of hydrogen atom.

2. In form of an electron.

3. In form of H₂O.

4. In form of ATP.

Complete the given reaction of the cycle present in the mitochondrial matrix:

$\mathrm{A}+\mathrm{Acetyl}$ $\mathrm{CoA}+{\mathrm{H}}_2\mathrm{O}\stackrel{\mathrm{B}}{\to }\mathrm{Citric}$ $\mathrm{acid}$

1. A—Succinic acid; B—Pyruvate dehydrogenase.

2. A—Malic acid; B—Transacetylase.

3. A—OAA; B—Citrate synthase.

4. A— $\alpha$ -KGA; B$\alpha$ Thiokinase.
