Which of the following is not used for the cyclic process of cellular respiration of carbohydrates?

The synthesis of GTP in Krebs’ cycle is

In cellular respiration, where is FADH₂ produced?

In Kreb's cycle, a molecule of GTP is produced during the conversion of:
1. Citrate into Ketoglutarate
2. Succinyl-CoA into succinate
3. Succinate into malate
4. Malate into oxaloacetate

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.
