Relationship Between Cellular Respiration And Photosynthesis

Cellular Respiration and Photosynthesis are two processes that occur in a cell. Cellular respiration coverts glucose and oxygen into ATP and its byproducts, carbon dioxide and water, are what cause photosynthesis to occur which is then converted into glucose and ATP and then release oxygen. Photosynthesis occurs in the chloroplast while cellular respiration occurs in the mitochondria. The glucose for cellular respiration is first split in the cytoplasm during the process glycolysis then the Kreb’s cycle takes place in the matrix of the mitochondria and finally the electron transport chain occurs in the inner membrane of the mitochondria. Photosynthesis has two stages, the light dependent reactions occur in the thylakoid and the light independent reactions occur but cannot occur without the products form the light dependent reactions.
The electrons used in the electron transport chain are transferred from the glucose to an electron acceptor (NAD) which then becomes (NADH) which is then carried to the electron transport chain and once it is there it becomes NAD again and is able to be reused. Another place that the electron can come from is FADH2 but, FADH2 and NADH both come from glycolysis and the citric acid cycle. In photosynthesis the electrons come from H2O which is split so O2 can be released because it is a byproduct from this process, this happens because the electron get excited and they are transferred to the primary electron acceptor. In the final step of the electron transport in photosynthesis the electron is transported to carriers called NADPH. In cellular respiration the electrons are transferred to oxygen which makes H2O which is the released from the process because it is a byproduct. In both of these processes ATP is needed so it needs to be generated as well, cellular respiration generates ATP
