What chemical changes occur during respiration?
What chemical changes occur during respiration?
Respiration is a chemical change as new substances like carbon dioxide and water are formed. Also there is change in the mass as glucose is oxidised by oxygen and heat is released. This change is permanent. All these factors conclude that respiration is a chemical change.
What type of reaction is respiration chemical or physical?
Respiration is a chemical reaction which takes place in all livings cells and releases energy from glucose.
How do you demonstrate cellular respiration?
Plants absorb carbon dioxide and then convert it into oxygen. One of the easiest ways to observe the respiration process at work is to get a potted plant and wrap the leaves in plastic wrap. Next, put your wrapped plant in a sunny place. In a few hours, you will see that the plastic has become moist.
What type of chemical change is cellular respiration?
catabolic reactions
The reactions of cellular respiration are catabolic reactions. In catabolic reactions, bonds are broken in larger molecules and energy is released. In cellular respiration, bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds.
Is breathing a physical or chemical change?
physical change
Is breathing a chemical change or physical change? Breathing is a chemical change as during breathing oxygen is taken inside and carbon dioxide and water are released.
What are some real life examples of cellular respiration?
An example of cellular respiration in plants is the use of photoautotrophic processes to obtain the glucose needed for cellular respiration. This means that plants can use the light energy they acquire from the sun to yield glucose and oxygen.
What factors affect cellular respiration lab answers?
Various factors, such as temperature change, will affect respiration, as well as the chemical oxidation of glucose. Oxygen consumption during respiration can then be measured as a change in gas volume by using a respirometer.
Is cellular respiration a physical or chemical change?

Respiration is a chemical change as new substances like carbon dioxide and water are formed. Also there is change in the mass as glucose is oxidised by oxygen and heat is released. This change is permanent. All these factors conclude that respiration is a chemical change.
What are the 5 phases of respiration?
Terms in this set (5)
- 1) Pulmonary Ventilation. Movement of air in and out of the lungs passage (Thorax and Diaphragm).
- 2) External Respiration. Exchange of gases between air and blood at pulmonary capillaries (Alveoli).
- 3) Transport of gases through blood vessels.
- 4) Internal Respiration.
- 5) Cellular Respiration.
