Question

question 1 1 pts at the end of glycolysis, the original carbons of the glucose molecule form six molecules of carbon dioxide two molecules of pyruvic acid two molecules of nadh two molecules of citric acid two molecules of fructose

Explanation:

Glycolysis is the metabolic pathway that breaks down glucose. One glucose molecule (6 - carbon) is converted into two pyruvic acid molecules (3 - carbon each) at the end of glycolysis. Carbon - dioxide is produced in later stages of cellular respiration like the citric acid cycle. NADH is an electron - carrier produced during glycolysis but not a carbon - containing end - product. Citric acid is part of the citric acid cycle and fructose is a different sugar molecule.

Answer:

Two molecules of pyruvic acid
