Detailed explanation-1: -Q. Photosynthesis and cellular respiration both involve the use and release of gases. Which statement correctly identifies the role of gases in the two processes? Photosynthesis and cellular respiration both use carbon dioxide and release oxygen.
Detailed explanation-2: -Photosynthesis and cellular respiration both use carbon dioxide and release oxygen.
Detailed explanation-3: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
Detailed explanation-4: -For instance, photosynthesis and cellular respiration both involve a series of redox reactions (reactions involving electron transfers). In cellular respiration, electrons flow from glucose to oxygen, forming water and releasing energy.
Detailed explanation-5: -The correct option is c. The process of photosynthesis results in the evolution of oxygen.
