It is produced by cellular respiration.
In cellular respiration oxygen reacts with glucose to form carbon dioxide, water, and energy tor be used by the cell.
CO2
The red blood cells collect waste products (CO2) from the cell.
it is because inhaled CO2 comes in direct contact with our lungs,which spread gases throughout the body cells, if CO2 enters in cells,it reacts with haemoglobin which forms carbaminohaemoglobin, and it's dangerous for health. This is not the matter when we drink soda mixed with CO2.
CO2
Red blood cells.
oxygen
Oxygen, CO2, proteins.
diffusion: - the movement of molecules from high to low concentrations. carbon dioxide is in higher concentration outside the leaf than inside so it DIFFUSES into the leaf THROUGH THE STOMATA and moves through the air spaces diffusing into the mesophyll cells for photosynthesis.
The respiratory system gets the oxygen from the air and releases CO2 from our body. The circulatory systemdistributes oxygen to individual cells and carries CO2 waste to the respiratory system.
molecules such as: CO2, O2, etc
carbon dioxide or CO2
They Collect CO2 from Your Lungs as They Are Constantly being pumped around the body therefore collecting Co2 Emissions every time they pass to your lungs.
