True or False: Muscle tissue contains carbon.

Muscle tissue contains carbon because all organic molecules, including proteins, lipids, carbohydrates, and nucleic acids, are made up of carbon atoms. Muscle tissue is primarily composed of muscle cells (myocytes), which contain proteins like actin and myosin that play a critical role in muscle contraction. These proteins, along with other molecules found in muscle tissue, are organic compounds, thus inherently contain carbon.

The composition of muscle tissue reveals that carbon is an essential element found in the biomolecules that make up the cells. All living tissue, including muscles, requires carbon as a fundamental building block for structure and function. Therefore, the statement that muscle tissue contains carbon is true.
