Place the following components of branched-chain amino acid metabolism in order from first to last. _____ 1. Alanine is deaminated in the liver into pyruvate and nitrogen. _____ 2. Nitrogen enters the urea cycle. _____ 3. The branched-chain amino acid is transaminated in the muscle. _____ 4. Pyruvate enters gluconeogenesis. _____ 5. The carbon skeleton is used to make energy, glucose, or fat, and the nitrogen is used to make the nonessential amino acid alanine.

Protein consumption above _____ is unlikely to result in additional muscle gains.
