Question

What is true about the function of the electron transport system (ETS)?

It produces two molecules of ATP and one molecule of NADH as a result of electron transfer during the breakdown of a six-carbon sugar into pyruvic acid in the endoplasmic reticulum of the cell.

It is a system that produces four ADP molecules within the lysosome of the cell by transferring free electrons from the cyclical process of metabolizing pyruvic acid into NADH and FADH2.

It is a system located in the mitochondrion of the cell that transfers electrons during the process of glycolysis to produce 16 molecules of ADP and 6 molecules of NADH.

It has the ability to generate 34 molecules of ATP for every molecule of glucose that is broken down as a result of a series of chemical reactions that occur in the cristae of the mitochondrion.

Answer 1

It has the ability to generate 34 molecules of ATP for every molecule of glucose that is broken down as a result of a series of chemical reactions that occur in the cristae of the mitochondrion.

Step-by-step explanation:

It was correct answer on my test.

Answer 2

The correct answer is the last option.

The first option does not make sense as the electron transport chain makes the most ATP from the whole ATP synthesis cycle including glycolysis and the Kreb's Cycle. It also does not make NADH, but instead splits NADH into NAD- and H+. The H+ are used later to make ATP.

The second option also does not make sense as a "lysosome" is a digestive "pocket" in the cell, used for taking in and digesting food for the cell.

The third option also does not make sense as it does not produce NADH and is not during glycolysis. The electron transfer chain breaks up NADH and FADH2 and is the last step in the ATP synthesis process, after glycolysis and Kreb's Cycle.

The last option is correct. The electron transfer chain has the ability to make 34 molecules of ATP (in theory; so in real-life this does not always happen). The electron transfer chain does break down several compounds derived from glucose in a series of chemical reactions that do occur in the cristae of the mitochondrion.
