The Krebs cycle does not directly pass electrons at a time. It generates electron carriers in the form of NADH and FADH2 by oxidizing acetyl-CoA to produce ATP and transfer electrons to the electron transport chain for further energy production.
In the Krebs cycle (also known as the citric acid cycle), three main electron carriers are produced per acetyl-CoA molecule: one molecule of NADH and one molecule of FADH2, along with one molecule of GTP (which can be converted to ATP). Since each glucose molecule results in two acetyl-CoA molecules entering the cycle, a total of six NADH, two FADH2, and two GTP (or ATP) are generated from one glucose molecule.
For each molecule of glucose consumed, the Krebs cycle (also known as the citric acid cycle) occurs twice. This is because one glucose molecule is broken down into two molecules of pyruvate during glycolysis, and each pyruvate is then converted into acetyl-CoA, which enters the Krebs cycle. Thus, for every glucose molecule, the cycle runs twice, producing energy carriers such as NADH and FADH2.

The main electron carriers in the Krebs cycle are NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide). These molecules are responsible for carrying electrons to the electron transport chain where ATP is produced.

The main electron carriers of the Krebs cycle are NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide). These molecules accept electrons and transport them to the electron transport chain for ATP production.
NAD+ and FAD are electron carriers that function in the Krebs cycle to accept and transport electrons from various reactions within the cycle. They play a crucial role in transferring these electrons to the electron transport chain for ATP production.
The Krebs cycle runs twice for each molecule of glucose consumed.
Type your answer here... A four-carbon molecule
The molecule you are referring to is NAD+ (nicotinamide adenine dinucleotide). It acts as a coenzyme electron carrier in the Krebs cycle by accepting and donating electrons during the oxidation-reduction reactions that occur in the cycle.
High-energy electrons from glycolysis and the Krebs cycle are ultimately transferred to oxygen molecules during oxidative phosphorylation in the electron transport chain to produce ATP.
The starting molecule for the Krebs cycle is acetyl-CoA, which enters the cycle by combining with oxaloacetate to form citrate.
