If one molecule of glucose undergoes the reaction of glycolysis, what is produced?(1 point) Responses 1 ATP, 3 NADH, and 1 Pyruvate 1 ATP, 3 NADH, and 1 Pyruvate 4 ATPs, 6 NADH, and 2 FADH2 4 ATPs, 6 NADH, and 2 FADH2 2 ATPs, 2 NADH, and 2 Pyruvate 2 ATPs, 2 NADH, and 2 Pyruvate 3 NADH and 1 FADH2

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.**

What are the functions of the high-energy electrons in the electron transport chain?(1 point) Responses They make ATP from ADP. They make ATP from ADP. They carry NADH and FADH2. They carry NADH and FADH 2 . They create ATP synthase. They create ATP synthase. They hold water bonds.

The primary function of the high-energy electrons in the electron transport chain is:

**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.

What is the third step in cellular respiration?(1 point) Responses glycolysis glycolysis the Krebs cycle the Krebs cycle the electron transport chain the electron transport chain the citric acid cycle

The third step in cellular respiration is:

**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

How many electrons must move down the Electron Transport Chain before energy is made?(1 point) Responses 2 2 5 5 3 3 4 4

In the context of the electron transport chain (ETC) in cellular respiration, each NADH donates 2 electrons and each FADH2 donates 2 electrons to the chain. However, the question about "how many electrons must move down the ETC before energy is made?" doesn't have a specific numerical answer, as energy is harnessed continuously as electrons move through the chain—not requiring a set number of electrons to initiate energy production.

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!

Which 3-carbon molecule is one of the final products of glycolysis?(1 point) Responses ADP ADP oxaloacetic acid oxaloacetic acid NAD+ NAD+ pyruvic acid

The 3-carbon molecule that is one of the final products of glycolysis is:

**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.
