Final answer:
Cholesterol, glucagon (and glycogen), and chylomicrons (and fatty acids) can be converted into intermediates of aerobic respiration to harvest energy, linking with the glycolysis pathway.
Step-by-step explanation:
Three compounds that can be converted into intermediates of aerobic respiration and be utilized to harvest their stored energy are cholesterol, glucagon (and glycogen), and chylomicrons (and fatty acids). These compounds are involved in common metabolic pathways and their breakdown products integrate with the glucose catabolism pathway or glycolysis to ultimately generate ATP, the energy currency of the cell.
Cholesterol and triglycerides can be converted to glycerol-3-phosphate, which continues through glycolysis. Glucagon and glycogen can be converted to 3-phosphoglyceraldehyde, an intermediate of glycolysis. Chylomicrons and fatty acids get converted to 1,3-bisphosphoglycerate that proceeds in glycolysis, forming pyruvate, which enters the Krebs cycle.
