which 3-carbon molecule is one of the final products of glycolysis? ( 1 point )
A.) oxaloacetic acid
B.) ADP
C.) pyruvic acid
D.) NAD+
C.) pyruvic acid
The 3-carbon molecule that is one of the final products of glycolysis is C.) pyruvic acid.
The final product of glycolysis is pyruvic acid, which is a 3-carbon molecule. To arrive at this answer, you can follow the steps of glycolysis and understand the metabolic process involved.
Glycolysis is the initial step in the breakdown of glucose to release energy. It takes place in the cytoplasm of the cell and involves a series of enzymatic reactions. During glycolysis, a molecule of glucose is converted into two molecules of pyruvic acid (also called pyruvate).
To find the answer to the question, you need to identify the final product of glycolysis that is a 3-carbon molecule. By eliminating the options, you can conclude that the correct answer is C.) pyruvic acid, as all the other options are not the products of glycolysis.
Oxaloacetic acid (option A) is a 4-carbon compound, ADP (option B) is not a product of glycolysis, and NAD+ (option D) is a coenzyme involved in the reactions of glycolysis, but it is not a final product.
Therefore, the correct answer is C.) pyruvic acid.
