Answer:
Fill in the blanks:
In photosynthesis, light energy is transformed chemical energy carbon dioxide gas is released. In cellular respiration, a glucose molecule is broken down and carbon dioxide gas is released.
Explanation: Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct. During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
