Photosynthesis uses those products from cellular respiration as its reactants and in turn produces glucose and oxygen- the reactants needed for cellular respiration.
Energy Transformation: Both Cellular Respiration and Photosynthesis need to transform energy into different forms in order for their reactions to initially take place and continue onward.
And to reward you for reading through all that, here's a cute little song I found on youtube about the relationship between cellular respiration and photosynthesis.
The NAD and FAD are then reduced in the following few steps so that their reduced forms NADH and FADH2 may carry the electrons onto the next part of cellular respiration.
In respiration energy is released fromsugars when electrons associated with hydrogen are transported to oxygen (theelectron acceptor), and water is formed as a byproduct. The mitochondriause the energy released in this oxidation in order to synthesize ATP. Inphotosynthesis, the electron flow is reversed, the water is split (not formed),and the electrons are transferred from the water to CO2 and in theprocess the energy is used to reduce the CO2 into sugar. Inrespiration the energy yield is 686 kcal per mole of glucose oxidized to CO2,while photosynthesis requires 686 kcal of energy to boost the electrons from thewater to their high-energy perches in the reduced sugar -- light provides thisenergy.
Photosynthesis Similarities Differences The Relationship Between the Processes Works Cited There are a number of similarities between these two series of reactions such as their equations, transformation of energy, exchange of gases, the Eletron Transport Chain and Chemiosmosis, and the theory of endosymbiosis.
