This isn't even technically true. One GTP molecule is produced which produces one ATP molecule.
The Krebs cycle produces tons of energy, but not in the form of ATP directly. The Krebs cycle (or TCA cycle) results in reducing potential molecules; NADH and FADH2 specifically. These molecules are shuttled through the electron transport chain to produce energy.
3 NADH molecules and 1 FADH molecule is produced for every turn of the Krebs cycle. One molecule of glucose will result in two turns of the Krebs cycle because two pyruvate molecules are the result of one glucose molecule (pyruvate if fed into the Krebs cycle after it is converted into acetyl-CoA). So, one glucose molecule = 6 NADH and 2 FADH molecules (and 2 GTP molecules)
In the electron transport chain 1 NADH molecule = 3 ATP. 1 FADH2 molecule = 2 ATP. From here the math is pretty straight forward
6 NADH molecules = 18 ATP
2 FADH molecules = 4 ATP
2 GTP molecules = 2 ATP
If you ever read something saying the number of ATP molecules produced from a glucose molecule is between 30-38 ATP do not be confused. This is simply the number for: glycolysis, TCA cycle, and oxidative phosphorylation (electron transport chain) added together. We only get about 30 ATP molecules out of it though because the process is not perfect.

∙ 12y agoThe Krebs cycle does not produce ATP directly, it produces high energy reduced compounds (FADH2 and NADH) which are then used to power the formation of ATP through the electron transport chain (ETC) and oxidative phosphorylation. In total 36 ATP are yielded from cellular respiration, 34 of them from the oxidative phosphorylation powered by FAD2 and NADH and 2 from glycolysis.

What is produced during the Krebs cycle?
The KREBS cycle turns a sugar molecule into a number of smaller molecules, whose main function is to supply very small packets of energy to cells. There are a number of molecules produced, of which the most common is Adenine triphosphate, aka ATP (which is used to "carry" energy around the body) This cycle is of first importance to all animals; anything which interferes with the Krebs cycle kills the organism very rapidly.

How many turns can a single glucose molecule drive the Krebs cycle?
A single glucose molecule is able to drive the Krebs cycle 2 times. The Krebs Cycle is the series of chemical reactions that take place to provide all aerobic organisms with the ability to make energy.
How many FADH molecules does the Krebs cycle produce during cellular respiration?
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.
Before Krebs cycle can proceed pyruvate must be converted into what?
Pyruvate is converted to acetyl-CoA before entering the Krebs cycle.
What happened to CO2 produced during the Krebs cycle?
it turns into your mom! you got powned

How many ATP molecules are produced from the kreb cycle?
directly, without using the electron transport chain there is one ATP per turn of the Krebs cycle, and two turns per glucose molecule.
Before Krebs cycle can proceed pyruvate must be converted into what?
Pyruvate is converted to acetyl-CoA before entering the Krebs cycle.
Is nadph formed during the Krebs cycle?
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)
What are the products of 6 turns of the Calvin cycle?
2 molecules of triose phosphate are made from the reaction of every 6 turns of the cycle source: bio major
How many passes through the kreb's cycle are required to break down a glucose molecule completely?
It's completely broken down in 2 turns of the Krebs cycle (:
What is the total NADH produced in one turn of the citric acid cycle?
there are 6 Nadph2 produced when it turns twice in the kreb cycle because there are 3 NAdH and when you use the kreb cycle twice the equation would be 3 nadh + p= 3 nadph * 2 = 6 NADPH2 - sixth grader in jhs 157
What electron carriers are produced in the Krebs cycle?
There are two electron carriers produced in the citric acid (Krebs Cycle). The first is NAD+ or NADH in its reduced form. The other is FAD+ which becomes FADH2 after being reduced. One turn of the citric acid cycle produces 1 and 3 molecules of FADH2 and NADH respectively.
