electron carriers

The net yield from one turn of the Krebs cycle (also known as the citric acid cycle) is three NADH, one FADH2, one GTP (or ATP), and two CO2 molecules. These electron carriers (NADH and FADH2) are crucial for the electron transport chain, where they contribute to ATP production. Overall, the Krebs cycle plays a vital role in cellular respiration, providing energy and intermediates for various metabolic processes.
In the citric acid (Krebs) cycle, each turn of the cycle produces 1 molecule of ATP directly. However, the majority of ATP is generated in the electron transport chain following the cycle, where approximately 30-32 molecules of ATP are produced from the energy released during the oxidation of NADH and FADH2.
It is changed into Acetyl CoA, which is then used in the citric acid cycle (aka Krebs Cycle).
In one turn of the Krebs cycle (also known as the citric acid cycle), each acetyl-CoA that enters produces three NADH and one FADH2. Since one glucose molecule generates two acetyl-CoA molecules during glycolysis, the total electron carriers produced from one glucose molecule are six NADH and two FADH2. Therefore, the total number of electron carriers made in the Krebs cycle from one glucose molecule is eight.
Definitely! Per ever glucose that passes through cellular respiration, 6 NADH are produced during the Krebs Cycle. (Precisely, 3 NADH are produced per turn of the Krebs Cycle and 1 glucose molecule causes the Krebs Cycle to turn twice. Therefore, 2 turns * 3 NADH per turn = 6 NADH)
From glycolysis two pyruvates are produced per molecule of glucose. Pyruvate is converted to acetyl CoA which enters the Kreb's cycle. Therefore, one molecule of glucose eventually creates 2 turns of the Krebs cycle. The cycle produces 1 ATP, 3 NADH, and 1 FADH2 per turn. So for each molecules of glucose you will have 2 FADH2.

From the cycle itself, two molecules of CO2 are released. One from Isocitrate to alpha-Ketoglutarate (with an Oxalosuccinate molecule as an intermediate compound), and other in the step from alpha-Ketoglutarate to Succinyl-CoA.
The Krebs cycle generates 1 ATP molecule per turn through substrate-level phosphorylation. Due to the cycle occurring twice per glucose molecule, a total of 2 ATP molecules are produced per glucose molecule entering the cycle.

Each turn of the Kreb's cycle must regenerate oxaloacetate.
In the citric acid (Krebs) cycle, each turn of the cycle produces 1 molecule of ATP directly. However, the majority of ATP is generated in the electron transport chain following the cycle, where approximately 30-32 molecules of ATP are produced from the energy released during the oxidation of NADH and FADH2.
It is changed into Acetyl CoA, which is then used in the citric acid cycle (aka Krebs Cycle).

The Krebs cycle produces 1 ATP molecule per cycle through substrate-level phosphorylation. Since the cycle completes twice for each glucose molecule entering glycolysis, a total of 2 ATP molecules are generated from the Krebs cycle per glucose molecule metabolized.
