glycolysis
When you go from:
Glyceraldehyde-3-Phosphate --->1,3 bisphosphoglycerate
There are 2NAD+ and 2Pi also reacting, and 2NADH as a product.
When calculating the free energy:
G=standard energy + RT ln (Keq)
To get Keq, we need concentrations of products and reactants. Now, nowhere, in any calculation have I ever seen a concentration for NAD+ or NADH used in these calculations. Are they so small, that we neglect them, or is an actual number used to represent their concentration ?
Thanx.
