Protein can indeed be utilized for energy through the conversion of amino acids in both glycolysis and the Krebs cycle. Amino acids can enter glycolysis and contribute to substrate-level phosphorylation, while acetyl CoA derived from amino acids can enter the Krebs cycle. Understanding the specific entry points of amino acids in these metabolic pathways is crucial for determining their role in energy production.
PREREQUISITESBiochemists, nutritionists, and students studying cellular metabolism will benefit from this discussion, particularly those interested in the energy contributions of proteins in metabolic pathways.
