Answer to Question #17066 in Biochemistry for Michael

Question

what are two identical things about photosynthesis and cellular respiration?

Answer 1

Both systems involve the movement of electrons through "electron transport chains" -> ATP is created through ATP synthase and an electrochemical gradient (Hydrogen ions) in a process called chemiosmosis.
Both take place in a organelle thought to have been ingested (reason for the double membranes of mitochondria and chloroplasts).
