To determine the products of glycolysis when one molecule of glucose undergoes the reaction, we can break down the process step by step.
During glycolysis, glucose (a 6-carbon molecule) is converted into two molecules of pyruvate (a 3-carbon molecule). This process involves several enzymatic reactions and ultimately results in the production of ATP and reducing agents like NADH.
Here's a breakdown of what occurs during glycolysis:
1. Glucose is phosphorylated, consuming one ATP and forming glucose-6-phosphate (a 6-carbon molecule with a phosphate group attached).
2. Glucose-6-phosphate is rearranged to form fructose-6-phosphate.
3. Another ATP is utilized to phosphorylate fructose-6-phosphate, forming fructose-1,6-bisphosphate (a 6-carbon molecule with two phosphate groups).
4. Fructose-1,6-bisphosphate is then cleaved into two molecules of glyceraldehyde-3-phosphate (a 3-carbon molecule with a phosphate group).
5. Each molecule of glyceraldehyde-3-phosphate undergoes several reactions, ultimately producing two molecules of pyruvate. In this process, two molecules of NADH and four molecules of ATP are generated.
To summarize:
- For each molecule of glucose that undergoes glycolysis, the net production is 2 ATP molecules (four ATPs are produced, but two ATPs are initially consumed) and 2 NADH molecules.
- Therefore, the correct answer is: 2 ATPs, 2 NADH, and 2 Pyruvate.
