  2. 1,3-Bisphosphoglyceric acid - Wikipedia

    en.wikipedia.org/wiki/1,3-Bisphosphoglyceric_acid

    1,3-Bisphosphoglyceric acid (1,3-Bisphosphoglycerate or 1,3BPG) is a 3-carbon organic molecule present in most, if not all, living organisms.It primarily exists as a metabolic intermediate in both glycolysis during respiration and the Calvin cycle during photosynthesis. 1,3BPG is a transitional stage between glycerate 3-phosphate and glyceraldehyde 3-phosphate during the fixation/reduction of ...

  3. Bisphosphoglycerate mutase - Wikipedia

    en.wikipedia.org/wiki/Bisphosphoglycerate_mutase

    1,3-BPG binds to the active site, which causes a conformational change, in which the cleft around the active site closes in on the substrate, securely locking it in place. [3] 1,3-BPG forms a large number of hydrogen bonds to the surrounding residues, many which are positively charged, severely restricting its mobility. Its rigidity suggests a ...

    en.wikipedia.org/wiki/Process_tracing_in_psychology

    These methods aim to study how the information is integrated after it has been introduced, and how that integration leads to a choice. [1] A popular model to study information integration is verbalized thoughts. Unlike movement-based methods, verbal methods are more direct, they aim to measure the internal process and not the behavior of the ...

  5. Phosphoglycerate kinase - Wikipedia

    en.wikipedia.org/wiki/Phosphoglycerate_kinase

    Phosphoglycerate kinase (EC 2.7.2.3) (PGK 1) is an enzyme that catalyzes the reversible transfer of a phosphate group from 1,3-bisphosphoglycerate (1,3-BPG) to ADP producing 3-phosphoglycerate (3-PG) and ATP : 1,3-bisphosphoglycerate + ADP ⇌ glycerate 3-phosphate + ATP. Like all kinases it is a transferase. PGK is a major enzyme used in ...

  6. 2,3-Bisphosphoglyceric acid - Wikipedia

    en.wikipedia.org/wiki/2,3-bisphosphoglyceric_acid

    2,3-BPG is formed from 1,3-BPG by the enzyme BPG mutase.It can then be broken down by 2,3-BPG phosphatase to form 3-phosphoglycerate.Its synthesis and breakdown are, therefore, a way around a step of glycolysis, with the net expense of one ATP per molecule of 2,3-BPG generated as the high-energy carboxylic acid-phosphate mixed anhydride bond is cleaved by 2,3-BPG phosphatase.

  7. Pyruvate kinase deficiency - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_kinase_deficiency

    This is the second ATP producing step of the process and the third regulatory reaction. [7] [12] Pyruvate kinase deficiency in the red blood cells results in an inadequate amount of or complete lack of the enzyme, blocking the completion of the glycolytic pathway. Therefore, all products past the block would be deficient in the red blood cell.

    d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...

  9. Luebering–Rapoport pathway - Wikipedia

    en.wikipedia.org/wiki/Luebering–Rapoport_pathway

    In biochemistry, the Luebering–Rapoport pathway (also called the Luebering–Rapoport shunt) is a metabolic pathway in mature erythrocytes involving the formation of 2,3-bisphosphoglycerate (2,3-BPG), which regulates oxygen release from hemoglobin and delivery to tissues. 2,3-BPG, the reaction product of the Luebering–Rapoport pathway was first described and isolated in 1925 by the ...
