Oxygen
Yes. This occurs during cellular respiration.
During respiration, the body releases carbon dioxide as waste. This occurs when cells break down glucose and produce energy through a process called cellular respiration. Carbon dioxide is then exhaled from the body through the lungs.
During respiration what do consumers take in?
H2O and CO2
glucose is broken down in glycolysis during respiration to release energy
carbon dioxide and water
During respiration, oxygen is used by the body to break down food molecules and convert them into energy in the form of ATP (adenosine triphosphate). Carbon dioxide is produced as a waste product and is exhaled from the body.
Not always, only when your body cells run out of energy.
During exercise, cellular respiration is the process by which cells break down glucose to produce energy in the form of ATP. This energy is used by muscles to contract and perform physical activities. The increased demand for energy during exercise leads to an increase in cellular respiration to meet the body's energy needs.
To release oxygen or to requried energy
Respiration produces waste material in the form of carbon dioxide (CO2). During cellular respiration, cells break down glucose to produce energy, releasing CO2 as a byproduct which is then exhaled from the body.
During cellular respiration the Glucose is broken down. It may be in either of two processes- Aerobic respiration and anaerobic respiration. In Aerobic respiration there is break down of glucose in CO2 and H2O along with energy in presence of O2. This can be shown in following reaction C6H12O6 + O2 --------> CO2 + H2O + Energy And in anaerobic respiration glucose is broken down in any alcohol.
