Photosynthesis and cellular respiration are
very closely related in many different ways. They both use the electron transport chain, both occur in the autotrophs of the
world, both have a lot to do with energy, and they use the same equation(being that the products of cellular respiration are
the reactants in photosynthesis, and the products of photosynthesis are the reactants of cellular respiration).
During photosynthesis it uses the electron
transport chain to transport the electrons to convert light energy into chemical energy for it to be stored into ATP and NADPH.
In respiration, the aerobic respiration uses the electron transport chain to produce ATP and release energy.
Energy plays a very important role in the processes
of cellular respiration and photosynthesis. Energy is produced during photosynthesis. Inside of cellular respiration energy
is released, but can also produce up to 38 molecules of ATP for the food molecules needed to be inside of the plant and for
photosynthesis to start over!
