Internal respiration is the transfer of gas between the blood and cells. External respiration also known as breathing refers to a process of inhaling oxygen from the air into the lungs and expelling carbon dioxide from the lungs to the air. Exchange of gases both in and out of the blood occurs simultaneously.
How are photosynthesis and cellular respiration related to each other? Photosynthesis occurs in plants; cellular respiratory occurs in animal life forms. Both processes are used to harvest energy through electron transport. Scientists compare the processes of photosynthesis and respiration by studying the redox reactions present in both processes. Both release energy through the synthesis of ATP. However, redox reactions in photosynthesis and respiration occur in opposite directions.
