Q. Which process produces the most ATP when glucose is oxidized to carbon dioxide and water?
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
Q. Which process produces the most ATP?
electron transport chain
Q. Which stage of the complete oxidation of glucose produces the largest ATP yield?
In glycolysis 2 ATP molecules are produced from ADP. Further 2NADH2 produced, give 2×3 = 6 ATP, on oxidative phosphorylation. Similarly in Kreb’s cycle 2 ATP molecules are produced. So the greatest number of ATP molecules are produced in the electron transport chain.
Q. Which of the following yields the most ATP when glucose is completely oxidized?
Electron transport chain
Q. What is the final stage of respiration that creates the greatest number of ATP?
The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).
Q. What type of respiration produces the greatest amount of ATP?
Aerobic respiration produces much more ATP than anaerobic respiration.
Q. When glucose is completely oxidized the net gain of ATP in glycolysis?
In the second stage of aerobic oxidation, pyruvate formed in glycolysis is transported into mitochondria, where it is oxidized by O2 to CO2. These mitochondrial oxidation reactions generate 34 of the 36 ATP molecules produced from the conversion of glucose to CO2.
Q. Which are the gases involved in breathing 1 point?
The function of the respiratory system is to move two gases: oxygen and carbon dioxide.
Q. What is the percentage of carbon dioxide in the inhaled air?
Inhaled and exhaled air
| Gas | % in inhaled air | % in exhaled air |
|---|---|---|
| Oxygen | 21 | 16 |
| Carbon dioxide | 0.04 | 4 |
| Nitrogen | 79 | 79 |
| NB These figures are approximate. |
Q. What is the percentage of oxygen and carbon dioxide in inhaled and exhaled air class 7?
The amount of inhaled air contains 21% of oxygen and 0.04% of carbon dioxide, while the air we breathe out contains 16.4% of oxygen and 4.4% of carbon dioxide. This is because our cells use oxygen from the inhaled air to release energy and give out carbon dioxide as a byproduct.
Q. What happens if you breathe in carbon dioxide?
What are the potential health effects of carbon dioxide? Inhalation: Low concentrations are not harmful. Higher concentrations can affect respiratory function and cause excitation followed by depression of the central nervous system. A high concentration can displace oxygen in the air.
Q. How much carbon monoxide do we breathe out?
Indoor levels of CO range from 0.5-5 parts per million (ppm) but may reach higher values (up to 30 ppm).
Q. How long does CO stay in your body?
The half-life of carboxyhemoglobin in fresh air is approximately 4 hours. To completely flush the carbon monoxide from the body requires several hours, valuable time when additional damage can occur.
Q. How long does CO stay in your bloodstream?
Carbon monoxide gas leaves the body the same way it got in, through the lungs. In fresh air, it takes four to six hours for a victim of carbon monoxide poisoning to exhale about half of the inhaled carbon monoxide in their blood.
Q. How long does it take to get carbon monoxide poisoning?
This can happen within 2 hours if there’s a lot of carbon monoxide in the air. Long-term exposure to low levels of carbon monoxide can also lead to neurological symptoms, such as: difficulty thinking or concentrating.
