Photosynthesis vs. Aerobic Cellular
Respiration
„
„
These two life dependent processes relate to each other
because they are Complementary Processes
Photosynthesis creates glucose, which is used in
Aerobic Cellular respiration to store energy in the form of
ATP, which is also required for Photosynthesis to occur
– They fuel each other.

Mitochondrion
Both processes occur in a similar fashion with complementary
reactions and organelles.
Both organelles have double membranes
Both organelles have an Electron Transport System located
within a membrane (Thylakoid membrane of chloroplast, Inner
membrane of mitochondrion). These Electron Transport
Systems contain electron carriers and cytochromes, which allow
the electrons to release energy while travelling through the ETS
chain.
In both organelles, energy released from electrons in the ETS is
used to power proton pumps which move hydrogen ions to form
a hydrogen ion gradient.
Both processes use the movement of a hydrogen ion across an
electrochemical gradient through ATP Synthase to form ATP.
This process is defined as chemiosmosis.
