Comparing Photosynthesis and Cellular Respiration

Compare photosynthesis and aerobic cellular respiration by completing the table and writing `yes ' or `no ' in the correct column . Justify your responses in the `explanation row ' that follows each question . The first item is completed for you

Concept Photosynthesis Cellular Respiration

1 .Oxygen required to complete reaction no yes

Oxygen serves as the final electron acceptor in cellular respiration 2 . Produces molecules of oxygen yes no

The electrons that chloroplasts lost during the first stage of photosynthesis are recovered through a process called photolysis which

br requires water molecules and produces oxygen molecules 3 . Produces molecules of carbon dioxide no yes

CO2 is produced during the citric acid cycle of cellular respiration when acetyl-CoA is oxidized 4 . Requires the energy of sunlight to initiate yes no

Energy from light is used to excite electrons from chloroplasts allowing the start of the flow of electrons in the electron transport chain 5 . Glucose or other food molecules required to initiate no yes

The first stage of cellular respiration , called glycolysis , involves the breaking of the six-carbon glucose molecule into two three-carbon pyruvic acid 6 . Represents an endergonic reaction yes no

Photosynthesis requires an external source of light energy to complete the process whereas cellular respiration does not need an external source of energy 7 . Produces ATP energy from chemical energy in food no yes

The main function of cellular respiration is to generate and store energy in the form of ATP 8 . Heterotrophic organisms undergo this process no...
