Question 1 Report

Which of the following groups of substances are not six-carbon compounds?
Answer Details
The correct answer is "Pyruvate and cellulose" because both pyruvate and cellulose are not six-carbon compounds. Pyruvate is a three-carbon compound produced during glycolysis, while cellulose is a polymer made up of repeating glucose units and has a much larger molecular weight than glucose. The other options contain at least one six-carbon compound: glucose has six carbons, lactose is made up of glucose and galactose (both six-carbon compounds), and cellulose contains repeating glucose units.
