In what form is most of the energy from the Krebs cycle captured?
In what form is most of the energy from the Krebs cycle captured?
This produces citric acid, which has six carbonatoms. This is why the Krebs cycle is also called the citric acid cycle. After citric acid forms, it goes through a series of reactions that release energy. The energy is captured in molecules of NADH, ATP, and FADH2, another energy-carrying compound.
Does the Krebs cycle produce ATP or GTP?
Citric Acid Cycle (Krebs Cycle) The eight steps of the cycle are a series of redox, dehydration, hydration, and decarboxylation reactions that produce two carbon dioxide molecules, one GTP/ATP, and reduced forms of NADH and FADH2.
What happens if no oxygen is present for cellular respiration?
When oxygen is not present and cellular respiration cannot take place, a special anaerobic respiration called fermentation occurs. Fermentation starts with glycolysis to capture some of the energy stored in glucose into ATP. Some bacteria carry out lactic acid fermentation and are used to make products such as yogurt.
What are the end products of anaerobic respiration?
Aerobic respiration vs anaerobic respiration
| Aerobic | Anaerobic | |
|---|---|---|
| Oxygen | Needed | Not needed |
| Glucose breakdown | Complete | Incomplete |
| End product(s) | Carbon dioxide and water | Animal cells: lactic acid. Plant cells and yeast: carbon dioxide and ethanol |
| Energy released | Relatively large amount | Relatively small amount |
What is the respiration of end products?
End products of respiration are carbon dioxide, water and energy in the form of ATP.
What are the main steps in aerobic respiration where does it takes place?
Aerobic respiration involves four stages:
- glycolysis,
- a transition reaction that forms acetyl coenzyme A,
- the citric acid (Krebs) cycle, and an electron transport chain and.
- chemiosmosis.
