Two of the most important cellular energy cycles are aerobic cellular respiration and oxygenic photosynthesis. These two are critical in the continued sustainability of all life on earth as we know it. The two process several intricate stages in which the creation of cellular energy occurs, and have varied relationships with organelles located within the eukaryotic cell. Both processes are primordial and key in how life has evolved and become as diverse as we know it. Although aerobic cellular respiration and oxygenic photosynthesis are different processes, they are interdependent from one another, while exhibiting complementary energy cycles. Oxygenic photosynthesis is the process from which cells use sunlight to convert carbon dioxide and water into sugar where oxygen is liberated as a byproduct. Photosynthesis as a whole provides the basic energy source for a lot of unicellular, …show more content…
This pathway provides the energy needed for multiple cells to function correctly. Two of the major purposes of respiration is to release free energy by the oxidation of sugars or other organic substances and also to make ATP. It is carried out by NAD and FAD in the cytoplasm and mitochondria of living organisms. Aerobic respiration uses oxygen and receives electrons from decomposed structures. Respiration occurs in most if not all cells. The three major steps involved in cellular aerobic respiration are glycolysis, Krebs cycle and the electron transport chain. In the process of glycolysis, the present enzymes oxidize glucose and split it into carbon molecules producing ATP. For the Krebs Cycle, ATP is produced when the carbon molecules are oxidized to carbon dioxide. In the electron transport system, the NADH that came from the Krebs cycle is used and electrons are given off. Hydrogen, in this case, leaves and NADH is transformed into NAD plus. ATP is created because of the hydrogen ion
