During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Terms/Concepts: transpiration: the process by which plants produce water through their leaves; photosynthesis: the process of plants using carbon dioxide and water and light absorbed by chlorophyll; A plant uses sunlight and carbon dioxide from the air to produce food. It also produces water.

During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).

During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.

The products of cellular respiration are carbon dioxide and water. Carbon dioxide is transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled. ATP is generated in the process.

Krebs cycle (or Citric acid cycle) This breaks down the pyruvic acid to carbon dioxide. This produces 2 ATP and 6 NADH , for every glucose molecule entering glycolysis. The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out.

The short answer is that when plants are doing cellular respiration, they produce carbon dioxide and water. When they are doing photosynthesis, they make oxygen and sugar.

Here are 3 introductory avenues that you can experiment with in order to increase your CO2 tolerance.

1. Keep your mouth closed while sleeping.
2. Breath hold exercises while walking.
3. Incorporate nasal-only breathing to your exercise sessions.

Holding your breath also causes the amount of carbon dioxide building up in your body to cross the blood-brain barrier. Your brain notices this change and increases your body’s desire to inhale and exhale.

Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.
