Final answer:
The mnemonic 'Goodness Gracious, Father Franklin Did Go By Picking Pumpkins (to) Prepare Pies' is a tool to memorize the intermediates of glycolysis, which converts glucose into pyruvate in two phases.
Step-by-step explanation:
A mnemonic device used to remember the intermediates of glycolysis is: "Goodness Gracious, Father Franklin Did Go By Picking Pumpkins (to) Prepare Pies". Each word represents an intermediate compound in the glycolysis pathway: Glucose, Glucose-6-Phosphate, Fructose-6-Phosphate, Fructose-1,6-bisphosphate, Dihydroxyacetone phosphate, Glyceraldehyde-3-phosphate, 1,3-Bisphosphoglycerate, 3-Phosphoglycerate, 2-Phosphoglycerate, Phosphoenolpyruvate, Pyruvate.
Glycolysis is a sequence of reactions where a glucose molecule is converted to two three-carbon compounds called pyruvate. The first phase, known as the energy investment phase, consumes ATP to prepare the sugar molecule for cleavage, and in the second phase, known as the energy payoff phase, ATP and NADH are produced.
