Why does protein help build muscles?
Show answer & explanation
Answer: Amino acids repair muscle fibers
Amino acids repair muscle fibers ✓ — Correct! Exercise creates micro-tears in muscle fibers. Amino acids from protein repair and rebuild them stronger. That's why athletes need more protein!
Burns fat into muscle — Wrong. Fat can't turn into muscle—they're different tissues. Protein builds muscle through amino acids.
Provides energy for workouts — Wrong. Protein's main role is providing amino acids for muscle repair, not energy.
