What else can I help you with?
Is there more carbon dioxide in air or your breath?
After you breathe air IN, your body uses some (but not all) of the oxygen in it. A lot of that oxygen that your body uses get converted to carbon dioxide, and it's added to the air that you breathe out. So your exhaled air has a greater concentration of carbon dioxide than fresh air has.
How does exercise affect the amount of carbon released from the lungs?
Your body is an engine that uses fuel (food) to produce energy for you to do exercise. The fuel contains carbon from the carbohydrates you eat, and the body uses oxygen from the air to do a chemical reaction that combines the carbon with the oxygen to produce energy plus carbon dioxide. If you do exercise, you use more fuel and more oxygen, and you produce more carbon dioxide. The body has sensors that detect excess carbon dioxide in the blood, and they make you breathe faster to get rid of it.
What kind of reaction is responsible for the liberation of Carbon dioxide in red blood cells?
respiration- The body takes in oxygen and glucose and turns it into carbon dioxide. Glucose is a mix of Carbon D, oxygen, and water. The body uses the oxygen, gets rid of the carbon dioxide and uses some of the water( the rest of the water is waste).
Photosynthesis and respiration keep levels of oxygen and CO2 at equilibrium?
Photosynthesis occurs in plants and some bacteria. It occurs within the chloroplasts. It uses H2O, Light energy and CO2 and gives off O2 and glucose. Respiration occurs in plants and animals. It occurs within the mitochondria. It uses O2 and glucose to produce energy, CO2 and H2O
Why do the air you breathe out contain no oxygen?
The air you breathe out contains less oxygen because your body extracts oxygen from the air when you breathe in and uses it during cellular respiration to produce energy. As a result, the air you breathe out has a higher concentration of carbon dioxide and less oxygen.
Does the human body create carbon dioxide?
Yes, the human body creates carbon dioxide as a byproduct of cellular respiration. During this process, cells break down glucose to produce energy, releasing carbon dioxide as a waste product which is then exhales out from the body through the lungs.
When your body uses oxygen and nutrients it makes waste and what else?
C02 (Carbon Dioxide)
Why do you breathe out carbon dioxide than you breathe in oxygen?
There's a process called gas exchange which takes place in the lungs: put simply, both oxygen & carbon dioxide are transported around the body in the blood stream; when the blood reaches the lungs it does a trade - swapping waste CO2 (a by-product of the cellular respiration which is constantly going on in every cell in your body) for oxygen in the air you've just breathed in. So the air you breathe out contains that waste gas, plus the proportion of CO2 that was already in your last breath in.
Why do you exhale more carbon dioxide than you breathe in oxygen?
Carbon dioxide is an end product of the matabolism in humans and other higher animals. Sugars, fats and amino acids are broken down to produce energy for the body and carbon dioxide is an unwanted by-product which is returned to the lungs and exhaled.
Does a plant use oxygen to make carbon dioxide in photosynthesis?
Photosynthesis equation: carbon dioxide + light energy --> oxygen + sugar (energy) so they produce oxygen It is sometimes scientifically beneficial to breathe on or talk to your plants because when you exhale you release carbon dioxide and the plants use that by changing it to oxygen as a part of photosynthesis!
The most important signal that the brain uses to set the breathing rate as the level of blood?
The most important signal that the brain uses to regulate breathing rate is the level of carbon dioxide in the blood. When carbon dioxide levels rise, this triggers the brain to increase the breathing rate to expel excess carbon dioxide and bring more oxygen into the body.
In respiration do you breathe in oxygen and breathe out carbon dioxide?
Normal air is 79% nitrogen, 20% oxygen, and 1% of mixed other gasses such as carbon dioxide, argon, water vapor, and everything else. Your body uses oxygen and excretes carbon dioxide. The nitrogen and noble gasses aren't used by our bodies. When you breathe in, your lungs will exchange some of the oxygen in the air for carbon dioxide. When you breathe out, your exhaled breath contains 79% nitrogen, 16% oxygen, 3% carbon dioxide and about 1% water vapor, along with the other assorted gasses that are present in the atmosphere. Note that normal air contains about 20% oxygen, and your exhaled breath still contains about 16% oxygen. That's why mouth-to-mouth artificial respiration (sometimes called "rescue breathing") can keep people alive even though you've already breathed that air once.
