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 ...

The S 0.5 and h result in an inflection of the curve enzyme activity as a function of glucose concentration at about 4 mM. [15] In other words, at a glucose concentration of about 72 mg/dL, which is near the low end of the normal range, glucokinase activity is most sensitive to small changes in glucose concentration.

Glucose-6-phosphate dehydrogenase is the rate-controlling enzyme of this pathway [citation needed]. It is allosterically stimulated by NADP + and strongly inhibited by NADPH. [7] The ratio of NADPH:NADP + is the primary mode of regulation for the enzyme and is normally about 100:1 in liver cytosol [citation needed]. This makes the cytosol a ...
G6PD reduces NADP + to NADPH while oxidizing glucose-6-phosphate. [2] Glucose-6-phosphate dehydrogenase is also an enzyme in the Entner–Doudoroff pathway, a type of glycolysis. Clinically, an X-linked genetic deficiency of G6PD makes a human prone to non-immune hemolytic anemia. [3]
"The metabolic pathway of glycolysis converts glucose to pyruvate via a series of intermediate metabolites. Each chemical modification (red box) is performed by a different enzyme. Steps 1 and 3 consume ATP (blue) and steps 7 and 10 produce ATP (yellow). Since steps 6-10 occur twice per glucose molecule, this leads to a net production of energy."
The main product, glucose-1,6-bisphosphate, appears to have several functions: 1. Inhibition of hexokinase, an enzyme used in the first step of glycolysis. [2] 2. Activation of phosphofructokinase-1 (PFK-1) and pyruvate kinase, both of which are enzymes involved in activation of the glycolytic pathway. [2] [3] 3.
