Single turn of citric acid cycle yields :-1 FADH2, 2 NADH, 1 GTP1 FADH2, 3 NADH, 3 GTP1 FADH2, 3 NADH, 1 GTP3 FADH2, 1 NADH, 1 GTP

To clarify the output of a single turn of the citric acid cycle (Krebs cycle), it’s important to summarize the contributions of electron carriers and energy equivalents produced during the cycle. A single turn of the citric acid cycle (for one acetyl-CoA) generally yields the following:

1. 2 NADH: These are produced from isocitrate to alpha-ketoglutarate and alpha-ketoglutarate to succinyl-CoA.
2. 1 FADH2: This is produced from succinate to fumarate.
3. 1 GTP (or ATP): This is generated from succinyl-CoA to succinate through substrate-level phosphorylation.

To encapsulate the entire yield from a single turn of the cycle:

• NADH: 3
• FADH2: 1
• GTP (or ATP): 1

This reflects the major energy carriers that are generated per cycle. Note that the total output can vary slightly in different sources, but this provides a standard view aligned with metabolic pathways.

Summary:

The correct yields from a single turn of the citric acid cycle include:

• 3 NADH
• 1 FADH2
• 1 GTP (or ATP)

Always refer to specific metabolic contexts for varied outputs, but this is the generalized yield from one cycle.

In your question's phrasing, there seems to be some confusion regarding the numbers presented; however, the correct yield remains as stated above.
