Even though glycolysis only produces 2 ATP, gluconeogenesis has a cost of 6 ATP. Despite this, why does gluconeogenesis still occur?
The energy cost is offset by the production of NADH.
The glucose will eventually be used in the CAC to generate lots of ATP.
The energy cost is offset by the glucose that comes from the diet.
Gluconeogensis in the liver makes glucose for tissues that need to use glycolysis for energy.
