Hello,
I have a question. For one molecule of glucose are there six CO2 molecules released during cellular respiration? I'm looking at the kreb/ citric acid diagram and I'm not sure if it is four or six CO2 molecules being released. I'll appreciate your response. Thanks.
Hello! I can help you with that question.
During cellular respiration, glucose is broken down into carbon dioxide (CO2) and water (H2O). The Krebs or citric acid cycle is part of the cellular respiration process.
To determine the number of CO2 molecules released during the breakdown of one glucose molecule in the Krebs cycle, we can follow these steps:
1. Start with one molecule of glucose (C6H12O6).
2. In the presence of oxygen, glucose undergoes a series of reactions in the Krebs cycle.
3. In each cycle, one molecule of glucose enters the Krebs cycle and goes through a series of chemical reactions.
4. In one complete cycle of the Krebs cycle, two carbon dioxide (CO2) molecules are released.
5. Therefore, for one molecule of glucose, which goes through the Krebs cycle twice, a total of 4 CO2 molecules are released.
So, the correct answer is that during cellular respiration, for one molecule of glucose, a total of four CO2 molecules are released in the Krebs cycle.
I hope this explanation helps! Let me know if you have any further questions.
