Question

during glycolysis, what is a 6-carbon sugar molecule broken down into? 12-carbon sugar molecules 3-carbon sugar molecules 1-carbon sugar molecules 5-carbon sugar molecules

Explanation:

Glycolysis is the process of breaking down glucose (a 6 - carbon sugar) into two molecules of pyruvate, and each pyruvate is a 3 - carbon compound. So during glycolysis, a 6 - carbon sugar molecule is broken down into 3 - carbon sugar molecules. The option of 12 - carbon sugar molecules is incorrect as glycolysis is a breakdown process, not a building - up process to form larger carbon - containing molecules. 1 - carbon and 5 - carbon sugar molecules are not the products of glycolysis for a 6 - carbon sugar breakdown.

Answer:

B. 3 - carbon sugar molecules (assuming the options are labeled A, B, C, D with B being "3 - carbon sugar molecules")
