Quizplus · Accepted Answer

Leucine is an essential amino acid that plays a vital role in protein synthesis and regulates protein turnover in the body. During a period of fasting, the body's primary source of energy is glucose, which is depleted within a few hours. After that, the body starts breaking down glycogen and fatty acids to provide energy. As the fasting continues, the body starts breaking down muscle protein to synthesize glucose through a process called gluconeogenesis. Leucine is the most predominant amino acid in muscle protein, and it is catabolized to generate energy during periods of fasting. Therefore, D) leucine is the correct choice.
