(Figure 4.14). Much more ATP, however, is produced later in a process called oxidative phosphorylation. Oxidative phosphorylation is a process involving a flow of electrons through the electron transport chain, a series of proteins and electron carriers within the mitochondrial membrane. Overview of oxidative phosphorylation. ________ donates electrons to the electron transport chain. A . The Citric Acid Cycle In eukaryotic cells, the pyruvate molecules produced at the end of glycolysis are transported into mitochondria, which are sites of cellular respiration. You have just read about two pathways in glucose catabolismglycolysis and the citric acid cyclethat generate ATP. What Are the net inputs and net outputs of oxidative phosphorylation? Oxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. The two photosystems performing all of this magic are protein complexes that are similar in structure and means of operation. Direct link to markemuller's post It says above that NADH c, Posted 6 years ago. In eukaryotic cells, the pyruvate molecules produced at the end of glycolysis are transported into mitochondria, which are sites of cellular respiration. It is easier to remove electrons and produce CO2 from compounds with three or more carbon atoms than from a two-carbon compound such as acetyl CoA. Thus NADPH, ATP, and oxygen are the products of the first phase of photosynthesis called the light reactions. Meanwhile, the excited electron from PS I passes through an iron-sulfur protein, which gives the electron to ferredoxin (another iron sulfur protein). This step regenerates NAD+ and FAD (the oxidized carriers) for use in the citric acid cycle. Use this diagram to track the carbon-containing compounds that play a role in these two stages. Direct link to sophieciurlik's post When it states in "4. What does this mean for your table on the 'breakdown of one molecule of glucose'? (Note that not all of the inputs and outputs of oxidative phosphorylation are listed.)
