If one molecule of glucose undergoes the reaction of glycolysis, what is produced?
3 NADH and 1 FADH2
4 ATPs, 6 NADH, and 2 FADH2
1 ATP, 3 NADH, and 1 Pyruvate
2 ATPs, 2 NADH and 2 Pyruvate??
The correct answer is: 2 ATPs, 2 NADH, and 2 Pyruvate.
If one molecule of glucose undergoes the reaction of glycolysis, the products produced are: 2 ATPs, 2 NADH, and 2 Pyruvate.
To determine the correct answer, let's first understand the process of glycolysis. Glycolysis is the initial step in cellular respiration, where glucose is broken down into pyruvate.
During glycolysis, one molecule of glucose (C6H12O6) is converted into two molecules of pyruvate (C3H4O3). This process occurs in the cytoplasm of the cell and involves a series of enzymatic reactions.
Now let's break down the given options:
Option 1: 3 NADH and 1 FADH2
This option does not align with the products of glycolysis. NADH and FADH2 are involved in later stages of cellular respiration, specifically in the Krebs cycle and electron transport chain.
Option 2: 4 ATPs, 6 NADH, and 2 FADH2
This option also does not match the products of glycolysis. While glycolysis does produce ATP, it only produces a net gain of 2 ATP molecules. The production of 6 NADH and 2 FADH2 is incorrect, as these are generated in the later stages of cellular respiration.
Option 3: 1 ATP, 3 NADH, and 1 Pyruvate
This option is the correct answer. During glycolysis, one molecule of glucose produces a net gain of 2 ATP molecules. Additionally, it generates 2 molecules of NADH, which is a reduced form of NAD+.
Option 4: 2 ATPs, 2 NADH, and 2 Pyruvate
This option is incorrect since glycolysis only produces a net gain of 2 ATP molecules, not 2 ATPs individually. The correct number of pyruvate molecules produced from one glucose molecule is 2, not 2 Pyruvate.
Therefore, the correct answer is: 1 ATP, 3 NADH, and 1 Pyruvate.
