Short answer

Question: How many ATP are invested and how many are recovered from each molecule of glucose that follows the glycolytic pathway?

Step-by-step solution

Cellular respiration

Cellular respiration is the mechanism by which metabolic processes receive energy in the form of ATP from nutrients. Glycolysis is the initial phase in cellular respiration, and it happens to glucose.

Glycolytic pathway

To convert the glucose molecule into two molecules of pyruvate, energy is necessary at the start of glycolysis. Stage II of cellular respiration is reached by these two molecules. To break glucose down, two ATP molecules are required. As glycolysis develops, energy is liberated, which is then utilised to generate four ATP molecules. As a result, two more ATP molecules are gained during glycolysis. High-energy electrons are transferred to NAD+ molecules at this moment, resulting in the formation of two NADH molecules, which transport energy. In the third step of cellular respiration, NADH is utilised to produce additional ATP

Conclusion

Two ATP molecules are invested, and four ATP molecules are created by the glycolytic process.
