Muscle Cells: Autotrophic or Heterotrophic? Understanding Energy Needs

A muscle cell is heterotrophic.

Muscle cells are cells that are responsible for the contraction and relaxation of muscles. They require energy in the form of ATP to function, and they obtain this energy by breaking down glucose through the process of cellular respiration. Cellular respiration is a process that requires oxygen, so muscle cells are heterotrophic because they must take in nutrients and oxygen from their environment in order to survive.
