1. Question 1

   Q1. What is the net change in carbon skeleton structure when a single molecule of glucose undergoes glycolysis?

   • A) One 6-carbon glucose into one 3-carbon pyruvate
   • B) Two 3-carbon pyruvates into one 6-carbon glucose
   • C) One 6-carbon glucose into two 2-carbon acetates
   • D) One 6-carbon glucose into two 3-carbon pyruvates

   Answer: One 6-carbon glucose into two 3-carbon pyruvates

   Explanation: Glycolysis is a 10-step process that converts one 6-carbon glucose into two 3-carbon pyruvate molecules.
