The change in free energy, ΔG, for each step in the glycolysis pathway can be calculated using ΔG = ΔG°′ + RTln Q, where Q is the reaction quotient. This requires knowing the concentrations of the metabolites. All of these values are available for erythrocytes, with the exception of the concentrations of NAD + and NADH.
"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."
[1] Glycolysis can be regulated at different steps of the process through feedback regulation. The step that is regulated the most is the third step. This regulation is to ensure that the body is not over-producing pyruvate molecules. The regulation also allows for the storage of glucose molecules into fatty acids. [5]
A stylized pathway map of glycolysis. This pathway represents a stylized rendition of glycolysis. Step three and six are reversible and correspond to triose phosphate isomerase and glycerol 3-phosphate dehydrogenase, respectively. The network has four elementary flux modes, which are shown in the figure below. A stylized pathway map of glycolysis.
The location where glycolysis, aerobic or anaerobic, occurs is in the cytosol of the cell. In glycolysis, a six-carbon glucose molecule is split into two three-carbon molecules called pyruvate. These carbon molecules are oxidized into NADH and ATP. For the glucose molecule to oxidize into pyruvate, an input of ATP molecules is required.

It’s never too old to teach your pet a new hobby (or trick). For example, if you have a dog breed that’s made for running, like an aerodynamic sighthound or an energetic springer spaniel, the ...
G-6-P is most commonly created from glucose by the action of the enzymes glucokinase (see glycolysis step 1) or hexokinase. Through the action of several enzymes glycogen is built up: G-6-P is converted into glucose-1-phosphate (G-1-P) by the action of phosphoglucomutase (PGM), passing through the obligatory intermediate glucose-1,6-bisphosphate.
