Given below are two statements related to Kreb's cycle. Statement...

In the Krebs cycle, there are four oxidation steps where hydrogen atoms are removed and transferred to coenzymes. These steps are catalyzed by dehydrogenases:
1. Isocitrate to $\alpha$-ketoglutarate ($\text{NAD}^+ \rightarrow \text{NADH} + \text{H}^+$)
2. $\alpha$-ketoglutarate to succinyl-CoA ($\text{NAD}^+ \rightarrow \text{NADH} + \text{H}^+$)
3. Succinate to fumarate ($\text{FAD} \rightarrow \text{FADH}_2$)
4. Malate to oxaloacetate ($\text{NAD}^+ \rightarrow \text{NADH} + \text{H}^+$)
Thus, Statement (I) is correct.

During the conversion of succinyl-CoA to succinate, one molecule of GTP is synthesized through substrate-level phosphorylation. Since one molecule of citric acid undergoes one turn of the Krebs cycle, only one molecule of GTP is produced per molecule of citric acid oxidized, not two. Thus, Statement (II) is incorrect.

Therefore, Statement (I) is correct but Statement (II) is incorrect.

Answer: Statement (I) is correct but Statement (II) is incorrect.
