Chemical energy for respiration is stored in the bonds of
• oxygen molecules.
• glucose molecules.
• water molecules.
• carbon dioxide molecules.
The chemical energy for respiration is stored in the bonds of glucose molecules.
Chemical energy for respiration is primarily stored in the bonds of glucose molecules.
The correct answer is glucose molecules. Chemical energy for respiration is stored in the bonds of glucose molecules.
To arrive at this answer, we need to understand the process of respiration. Respiration is the process by which organisms convert glucose and oxygen into energy, releasing carbon dioxide and water as waste products.
Glucose is a carbohydrate that serves as the primary source of energy in living organisms. When glucose is broken down during respiration, its chemical energy is released. This energy is then used by cells to perform various functions.
Oxygen acts as the final electron acceptor in the process of respiration. It combines with glucose during cellular respiration and allows for the complete breakdown of glucose molecules, releasing energy for the cell.
Water and carbon dioxide are by-products of respiration. Carbon dioxide is produced as a waste product when glucose is broken down, and water is formed when oxygen atoms combine with hydrogen atoms during the energy-releasing reactions.
Therefore, while oxygen molecules, water molecules, and carbon dioxide molecules are involved in respiration, the chemical energy is primarily stored in the bonds of glucose molecules.
