When one molecule of glucose undergoes glycolysis, the products are 2 ATP, 2 NADH, and 2 pyruvate molecules. Therefore, the correct answer is:
**2 ATPs, 2 NADH, and 2 Pyruvate.**
**2 ATPs, 2 NADH, and 2 Pyruvate.**
**They make ATP from ADP.**
High-energy electrons are transferred through the chain, which drives the pumping of protons across the mitochondrial membrane, ultimately leading to the production of ATP via ATP synthase.
**the electron transport chain.**
Here's a brief overview of the sequence of steps in cellular respiration:
1. Glycolysis
2. The Krebs cycle (or citric acid cycle)
3. The electron transport chain
However, if you're referring to the function of how many electrons in general contribute to ATP production, then typically, for each NADH that enters the ETC, 2 electrons are transferred.
Thus, if the multiple-choice question is asking for the minimum number of electrons, since the most common entry point (from NADH) involves 2 electrons, the response would likely be:
**2.**
Please clarify if this is the intended interpretation of your question!
**pyruvic acid.**
Glycolysis converts one molecule of glucose into two molecules of pyruvic acid, along with a net gain of 2 ATP and 2 NADH.
