The enzyme that catalyzes step four is regulated by feedback inhibition of ATP, succinyl CoA, and NADH. The Citric Acid Cycle: The citric acid cycle, or Krebs cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidization of acetate—derived from carbohydrates, fats, and proteins—into carbon dioxide. The NADH and QH2 that is generated by the citric acid cycle is used by the oxidative phosphorylation pathway to generate energy-rich adenosine triphosphate (ATP). The pyruvate molecules then forms acetyl CoA and one molecule of carbon dioxide is released. In addition, one complete turn of the cycle converts three equivalents of nicotinamide adenine dinucleotide (NAD+) into three equivalents of reduced NAD+ (NADH), one equivalent of ubiquinone (Q) into one equivalent of reduced ubiquinone (QH2), and one equivalent each of guanosine diphosphate (GDP) and inorganic phosphate (Pi) into one equivalent of guanosine triphosphate (GTP). Its central importance to many biochemical pathways suggests that it was one of the earliest established components of cellular metabolism; it may have originated abiogenically. Steps three and four are both oxidation and decarboxylation steps, which release electrons that reduce NAD+ to NADH and release carboxyl groups that form CO2 molecules. If oxygen is present to drive subsequent reaction, pyruvate enters the mitochondria, where the citric acid cycle (also known as the Krebs Cycle) (Stage 2) and electron transport chain (Stage 3) break it down and oxidize it completely to CO 2 and H 2 O. substrate-level phosphorylation (A phosphate group is transferred from GTP to ADP.) This possesses a series of anaerobic reactions, such as the preparatory reaction. The cycle carries citric acid through a series of chemical reactions which gradually release energy and capture it in several carrier molecules. The citric acid cycle is exergonic in terms of overall free-energy changes. Almost all of the enzymes of the citric acid cycle are soluble, with the single exception of the enzyme succinate dehydrogenase, which is embedded in the inner membrane of the mitochondrion. NADH + H+. c. The citric acid cycle occurs in the mitochondria. Four control points exist for the citric acid cycle. Hot water (0.01 m3 /min) enters the tube side of a counter current shell and tube heat exchanger at 80°C and leaves at 50°C. 4 A glucose molecule is completely broken down to carbon dioxide and water in glycolysis and the citric acid cycle, but together these two processes yield only a few molecules of ATP. ascorbic acid has a molar mass of 176.14 g/mol .
