Multiple Choice
In glycolysis, the starting molecule (initial substrate) is which of the following?
A
Fructose-1,6-bisphosphate
B
Pyruvate
C
Glucose
D
Glycogen
Verified step by step guidance1
Understand that glycolysis is the metabolic pathway that breaks down glucose to produce energy in the form of ATP.
Recall that glycolysis begins with a six-carbon sugar molecule, which is the initial substrate for the pathway.
Identify the options given: Fructose-1,6-bisphosphate, Pyruvate, Glucose, and Glycogen.
Recognize that Fructose-1,6-bisphosphate is an intermediate formed after glucose is phosphorylated and rearranged, not the starting molecule.
Know that Pyruvate is the end product of glycolysis, and Glycogen is a storage form of glucose, not the direct starting substrate for glycolysis.
