Bone:
* Calcium Phosphate: This is the primary mineral component of bone, providing rigidity and strength.
* Collagen: This is a protein that provides flexibility and tensile strength to bone.
* Other Minerals: Bone also contains smaller amounts of other minerals like magnesium, sodium, and potassium.
Muscle:
* Proteins: Muscle is primarily made up of proteins, specifically:
* Actin: A thin filament protein involved in muscle contraction.
* Myosin: A thick filament protein involved in muscle contraction.
* Other structural proteins: Like titin and nebulin, which help maintain muscle fiber structure.
* Water: Muscle contains a significant amount of water, which is essential for proper function.
* Glycogen: This is a stored form of glucose that muscles use for energy.
* Creatine Phosphate: A high-energy molecule used for short bursts of energy in muscle.
In Summary:
* Bone is primarily mineral-based, with calcium phosphate providing its strength, and collagen providing its flexibility.
* Muscle is primarily protein-based, with actin and myosin being the key components for contraction.
