In TCA cycle, succinate is converted to ketoglutarate by the enzyme: How many molecules of CO2 are produced?

Question image

Understand the Problem

The question is asking for the number of molecules of CO2 produced during a specific part of the TCA (Krebs) cycle, specifically in relation to the conversion of succinate to ketoglutarate.

Answer

None. Succinate is not directly converted to ketoglutarate in the TCA cycle.

The final answer is none. Succinate is converted to fumarate, then to malate and oxaloacetate, and eventually enters the cycle again without directly converting to ketoglutarate. The conversion to ketoglutarate involves steps starting from isocitrate.

Answer for screen readers

The final answer is none. Succinate is converted to fumarate, then to malate and oxaloacetate, and eventually enters the cycle again without directly converting to ketoglutarate. The conversion to ketoglutarate involves steps starting from isocitrate.

More Information

The TCA cycle involves multiple steps where intermediates are converted, but succinate is transformed to fumarate, not directly to ketoglutarate.

Tips

A common mistake is confusing the order of reactions and intermediates in the TCA cycle.
