Which of the following is NOT a component of muscle composition?

Muscle composition primarily consists of water, proteins, and various enzymes. Each of these components plays a crucial role in muscle function and performance.

Water is essential for maintaining hydration within muscle cells, supporting metabolic processes, and facilitating nutrient transport. Proteins are the fundamental building blocks of muscle tissue, providing the structural framework necessary for muscle contraction and repair. Enzymes are also integral, as they catalyze various biochemical reactions necessary for energy production and muscle function.

While carbohydrates do play a role in energy metabolism and can be stored in muscle tissue as glycogen, they are not a direct structural component of muscle itself. Instead, carbohydrates are primarily used as a source of energy during physical activity. Therefore, carbohydrates can be considered less central to the composition of muscle compared to the other components listed. This context clarifies why carbohydrates are not categorized as a fundamental component of muscle composition.
