검증된 단계별 안내1
Begin by understanding the process of gluconeogenesis, which is the metabolic pathway that results in the generation of glucose from non-carbohydrate substrates.
Identify which of the given molecules can be converted into glucose through gluconeogenesis. Glycogen is a polysaccharide that can be broken down into glucose through glycogenolysis, making it a direct source of glucose.
Consider amino acids: Some amino acids can be converted into intermediates that enter gluconeogenesis, thus they can be used to produce glucose.
Evaluate nucleotides: These are primarily involved in genetic information storage and energy transfer (e.g., ATP) and are not typically converted into glucose for fuel.
Assess fatty acids: Fatty acids are broken down into acetyl-CoA units, which enter the citric acid cycle but cannot be converted into glucose due to the irreversible nature of the pyruvate dehydrogenase reaction.
