How many ATP are produced from acetyl Co A that goes through the electron transport system?
Each acetyl CoA that goes through the citric acid cycle produces 2 Carbon Dioxide, 3 Hydrogen ions, 3 NADH, and 1 FADH2. The chemical components of this reaction are then able to create 1 ATP via substrate level phosphorlyation in the Electron Transport Chain. More importantly however, each NADH makes 3 ATP and each NADH2 makes 2, so combined, the 3 NADH and 1 FADH2 produce 11 ATP, or 12 when combined with the one from substrate-level. Since there are 2 acetyl-CoA produced per glucose during glycolysis, a total of 24 ATP is made during the electron transport system, as opposed to 36 or 38 for all of cellular respiration.
However, all of these numbers are just theoretical. Slight imperfections and inefficiencies prevent most cells from ever actually achieving 100% of they yield as described. As a result, the total effective yield is closer to 28-30 for the overall process and only 9 or 10 ATP are actually produced per acetyl-CoA in the electron transport system.

What is the respiration - sequence of events?
The sequence of events in aerobic respiration is: glycolysis, formation of acetyl CoA, the Krebs cycle, the electron transport chain.
How are 3 carbon molecules broken down to?
Three-carbon molecules, such as pyruvate, are primarily broken down through cellular respiration. In the presence of oxygen, they enter the mitochondria and undergo oxidative decarboxylation, converting into acetyl-CoA while releasing carbon dioxide. This acetyl-CoA then enters the citric acid cycle (Krebs cycle) to be further oxidized, generating ATP and electron carriers like NADH and FADH2 for the electron transport chain, where most ATP is produced. In anaerobic conditions, pyruvate can be converted into lactate or ethanol instead.
Does tca cycle generate water?
No, the TCA cycle (also known as the citric acid cycle or Krebs cycle) does not directly generate water. Instead, it is a series of chemical reactions that converts acetyl-CoA into carbon dioxide, producing ATP and electron carriers like NADH and FADH2 in the process. Water is mainly generated through oxidative phosphorylation in the electron transport chain.
What is the sequence of events in the complete oxidation of glucose to ATP?
The oxidation of glucose to ATP is known as cellular respiration. High energy bonds are broken through the introduction of chemicals within the cell, energy is released, and stronger bonds are set in replacement and as waste product.
How many nadh and fadh are produced from Krebs cycle?
During one turn of the Krebs cycle (also known as the citric acid cycle or TCA cycle), three molecules of NADH and one molecule of FADH2 are produced. Since each glucose molecule yields two acetyl-CoA molecules, the overall yield from one glucose molecule is six NADH and two FADH2. These electron carriers are then utilized in the electron transport chain to generate ATP.
Acetyl-CoA is produced from?
Acetyl-CoA is produced from the oxidation of pyruvate in the mitochondria during the process of aerobic respiration. Pyruvate is first converted to acetyl-CoA by the pyruvate dehydrogenase complex, which involves a series of enzymatic reactions. Acetyl-CoA is a key molecule that enters the citric acid cycle to generate ATP through the electron transport chain.
What is the respiration - sequence of events?
The sequence of events in aerobic respiration is: glycolysis, formation of acetyl CoA, the Krebs cycle, the electron transport chain.
How many ATP is in NADH2?
In the citric acid cycle acetyl-CoA combines with oxaloacetate to create citrate. This molecule then goes through a series of 8 reactions to create 3 NADH, 1 FADH2, and 1 GTP/ATP. The cycle regenerates oxaloacetate and is then ready for entry of another molecule of acetyl-CoA to repeat the entire process.
How do glycolysis pyruvate processing. the Krebs cycle and the electron transport chain work together to provide energy for the cell?
When the cell gains gluclose, the process of glycolysis occurs and the gluclose is broken down down into pyruvate. In pyruvate processing, Acetyl CoA is produced nad then used in the Krebs Cycle. There, NADH and FADH2 are made and go to the electron transport chain, where water and ATP are made. *

What is the main order of events of cellular respiration?
1. Glycolysis 2. Acetyl-CoA formation 3. Citric Acid Cycle 4. Electron Transport Chain

Water is mainly generated through oxidative phosphorylation in the electron transport chain.
Is the formation of acetyl CoA aerobic or anaerobic?
The formation of acetyl CoA can occur through both aerobic and anaerobic pathways. In aerobic conditions, acetyl CoA is produced during the breakdown of glucose in the mitochondria. In anaerobic conditions, acetyl CoA can be derived from other molecules like fatty acids or amino acids through processes like beta-oxidation or deamination.
What is the sequence of events in the complete oxidation of glucose to ATP?
The oxidation of glucose to ATP is known as cellular respiration. High energy bonds are broken through the introduction of chemicals within the cell, energy is released, and stronger bonds are set in replacement and as waste product.
The stages of aerobic respiration are?
First stage is Glycolysis pyruvate is then turned into Acetyl CoA and enters the Krebs Cycle Second stage is Krebs Cycle Third stage is Electron transport chain
Most of the NADH that delivers high-energy electrons to the electron transport chain comes from?
Most of the NADH that delivers high-energy electrons to the electron transport chain comes from the citric acid cycle (Krebs cycle) during cellular respiration. This cycle generates NADH as a byproduct when converting acetyl-CoA to CO2, which is then used to produce ATP in the electron transport chain.
Where is the majority of the usable energy found at the completion of glycolysis acetyl CoA formation and the Krebs cycle?
The majority of the usable energy generated during glycolysis, acetyl CoA formation, and the Krebs cycle is stored in the high-energy phosphate bonds of ATP and NADH molecules. These molecules carry the energy to the electron transport chain, where it is used to produce more ATP through oxidative phosphorylation.
