Q: You are asked to look through a microscope at an unknown cell. you notice that it is striated (striped) and layered and has many mitochondria. what is the likely function of this cell group of answer choices?

Flexi Says: Cardiac muscle is found only in the walls of the heart. When cardiac muscle contracts, the heart beats and pumps blood. Cardiac muscle contains a great many mitochondria, which produce ATP for energy. This helps the heart resist fatigue. Contractions of cardiac muscle are involuntary, like those of smooth muscle. Cardiac muscle, like skeletal muscle, is arranged in bundles, so it appears striated, or striped.
