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.

At how many points during Krebs’ cycle NADH is produced?

$\mathrm{Pyruvic} \mathrm{acid} +\mathrm{CoA}+{\mathrm{NaD}}^{+}\stackrel{\mathrm{A}}{\to }$
$\mathrm{B}+{\mathrm{CO}}_2+{\mathrm{NADH}}^{+}+{\mathrm{H}}^{+}$ in the above given reaction of respiration what can be placed at the place of A and B respectively?

1. Iron and Citric acid.
2. Magnesium and Citric acid.
3. Dehydrogenase and Acetyl CoA.
4. Iron and Acetyl CoA
