Which of the following is a result of glycolysis? a) A net gain of four ATP per one glucose molecule. b) Conversion of FAD to FADH 2 . c) Conversion of one glucose molecule to two pyruvate molecules. d) Conversion of NADH to NAD + .

Okay, everyone. Which of the following is a result of glycolysis, the very first step in cellular respiration? Okay. Let's look at our answer choices. Which of the following results from glycolysis? A net gain of 4 ATP per 1 glucose molecule. While technically glucose does make 4 ATP, that is not its net production because technically it requires 2 of those 4 ATP to function. So, technically, it makes 2 net ATP. So this answer is not correct. Answer choice b says that glycolysis results in the conversion of f a d to f a d h 2. This is not going to be the electron carrier that glycolysis utilizes. Remember, glycolysis only utilizes NADH. This is not the answer we're looking for. Answer choice c says, glycolysis results in the conversion of 1 glucose molecule into 2 pyruvate molecules. This is a true statement. The major product created by glycolysis is 2 pyruvate molecules. Let's rule out answer choice d. Glycolysis results in the conversion of NADH to NAD plus. This is backwards. Technically, glycolysis turns NAD plus into NADH by giving it electrons from glucose. So this is not the answer. The correct answer here is answer choice c. Which of the following is a result of glycolysis? That is the conversion of 1 glucose molecule into 2 pyruvate molecules. Okay, everyone. Let's move on to our next video.

Verified step by step guidance

Understand that glycolysis is the process of breaking down one glucose molecule into two molecules of pyruvate, which occurs in the cytoplasm of the cell.

Recognize that glycolysis results in a net gain of two ATP molecules per glucose molecule, not four. This is because four ATP molecules are produced, but two are used during the process.

Identify that glycolysis involves the reduction of NAD+ to NADH, not the conversion of NADH to NAD+.

Note that FAD is not involved in glycolysis; it is part of the citric acid cycle and oxidative phosphorylation.

Conclude that the correct result of glycolysis is the conversion of one glucose molecule to two pyruvate molecules, along with a net gain of two ATP and the production of NADH.
