Question

If one molecule of glucose undergoes the reaction of glycolysis, what is produced?(1 point)
Responses

4 ATPs, 6 NADH, and 2 FADH2
4 ATPs, 6 NADH, and 2 FADH2

1 ATP, 3 NADH, and 1 Pyruvate
1 ATP, 3 NADH, and 1 Pyruvate

3 NADH and 1 FADH2
3 NADH and 1 FADH2

2 ATPs, 2 NADH, and 2 Pyruvate

Answer 1

When one molecule of glucose undergoes glycolysis, the products are:

**2 ATPs, 2 NADH, and 2 Pyruvate.**

So the correct response from the provided options is:

**2 ATPs, 2 NADH, and 2 Pyruvate** (this option was not listed in your original responses but this is the accurate answer).

If you meant one of the provided responses that closely resembles this, please double-check the options, as the exact products of glycolysis from one glucose molecule are indeed 2 ATPs and 2 NADH, producing 2 Pyruvate at the end of the pathway.

Answer 2

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 create ATP synthase.
They create ATP synthase.

They hold water bonds.
They hold water bonds.

They carry NADH and FADH2.

Answer 3

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

**They make ATP from ADP.**

As the high-energy electrons move through the chain, they help establish a proton gradient across the inner mitochondrial membrane, which ultimately drives the synthesis of ATP from ADP via ATP synthase.

Answer 4

What is the third step in cellular respiration?(1 point)
Responses

the electron transport chain
the electron transport chain

the citric acid cycle
the citric acid cycle

glycolysis
glycolysis

the Krebs cycle

Answer 5

The third step in cellular respiration is:

**the electron transport chain.**

The sequence of cellular respiration is glycolysis (first step), the citric acid cycle (also known as the Krebs cycle, second step), and then the electron transport chain (third step).

Answer 6

Answer 7

The correct answer is:

**2.**

In the electron transport chain (ETC), each pair of electrons (from NADH or FADH2) is transported through the chain. However, the specific question of "how many electrons must move down the Electron Transport Chain before energy is made?" is often interpreted in the context of what is necessary to generate a proton gradient and subsequently produce ATP.

Typically, the movement of **two electrons** results in the eventual production of ATP via ATP synthase. Therefore, **2 electrons** is the best answer in this context.

Answer 8

Which 3-carbon molecule is one of the final products of glycolysis?(1 point)
Responses

ADP
ADP

pyruvic acid
pyruvic acid

oxaloacetic acid
oxaloacetic acid

NAD+
NAD+

Answer 9

The correct answer is:

**pyruvic acid.**

Pyruvic acid (or pyruvate) is the 3-carbon molecule that is one of the final products of glycolysis. Each molecule of glucose is converted into two molecules of pyruvate during the glycolytic process.
