검증된 단계별 안내1
Step 1: Understand the four main types of biomolecules: carbohydrates, lipids, proteins, and nucleic acids, and their general functions in the body.
Step 2: Recognize that carbohydrates primarily provide energy, lipids serve as long-term energy storage and structural components, and nucleic acids store genetic information.
Step 3: Identify that proteins are composed of amino acids, which serve as the building blocks for muscle tissue, making them essential for muscle development.
Step 4: Note that proteins also play a critical role in muscle contraction through contractile proteins like actin and myosin within muscle fibers.
Step 5: Conclude that proteins are the biomolecules responsible for both building muscle tissue and supporting muscle contraction.
