A huge amount of water is held up on top of a cliff, with the potential to release a lot of energy when gravity is allowed to naturally pull it down through the dam. The end product of oxidative phosphorylation is (A) NADH (B) Oxygen (C) ADP (D) ATP + H2O. What is the Main Frame Story of The Canterbury Tales? Oxidative phosphorylation is a metabolic process which consists of series of biochemical reactions to bring bioenergetics changes by which ADP and P i (inorganic phosphate) are converted into ATP by utilizing the electrons and hydrogen ions from NADH or FADH 2 to O 2 via electron carriers involved in the electron transport chain.. You can test out of the Get the unbiased info you need to find the right school. 's' : ''}}. This is our bonus game but also the most important round, because now we will convert our tokens from the citric acid cycle (NADH and FADH 2) into tickets (ATP).This is where the bulk of ATP comes from in cellular respiration—not glycolysis nor the citric acid cycle, but oxidative … Sciences, Culinary Arts and Personal In most tissues, such as skeletal muscle, mitochondria are the main site of energy production through the oxidative phosphorylation pathway. To help visualize this property, keep the hydroelectric dam analogy in mind throughout the following discussion of oxidative phosphorylation, which uses falling electrons and hydrogen ions to do other work, like making ATP. These 2 sets of reactions are coupled and interrelated. Oxidative phosphorylation occurs in the mitochondria of all animal and plant tissues, and is a coupled process between the oxidation of substrates and production of ATP. The electron transport chain (also known as the respiratory chain) comprises 4 complexes located in the inner mitochondrial membrane. What are the products of Oxidative Phosphorylation? The cell taps this energy source by using enzymes to transfer phosphate groups from ATP to other compounds, which are then said to be phosphorylated. check_circle Expert Answer. Exam 2 - Chapter 7. In all, close to 300 proteins are needed for efficient OXPHOS activity.The overall process of oxidative phosphorylation is tightly controlled by transcriptional regulation at the level of DNA, translational effects via RNA levels and stability, by substrate feedback inhibition, and by post-translational modifications including phosphorylation and acetylation. The production of such substances, i.e., Hydrogen peroxide and superoxide, are unavoidable in the body, and can lead to an increased risk of cancer, inflammation and chronic disease.
