How many ATPs does cellular respiration produce?
Each pathway in cellular respiration produces ATP. Glycolysis specifically generates 4 ATP, but has a net gain of 2 ATP. There is another energy metabolite, NADH, that is also generated but to a lesser extent. For this lesson we will focus more on ATP.
What are the steps of glycolysis?
The first four steps in glycolysis involve the preparation of glucose into a molecule that's easily split in half: glucose 1,6-bisphosphate. Glucose 1,6-bisphosphate is split into two molecules of glucose 3 phosphate or G3P. G3P continues to change and winds up as pyruvate. Remember, glycolysis generates two pyruvate molecules.
