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.
The Krebs cycle utilizes enzymes to break down molecules like glucose and fatty acids, producing NADH as a result. NADH is an important molecule that carries energy to the electron transport chain for ATP production in cellular respiration.
The electron carrier molecules of the Krebs cycle are NADH and FADH2. In the Calvin cycle, the electron carrier molecule is NADPH.
The main function of the Krebs cycle is the complete oxidation of glucose to produce ATP. It is also referred to as the citric acid cycle.
The Krebs cycle runs twice for each molecule of glucose consumed.
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.
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.
