Question

all of the following statements regarding cardiac muscle tissue are true, except: cardiac muscle cells are almost totally dependent on aerobic respiration to obtain the energy needed to continue contracting. cardiac muscle cells are much larger than skeletal muscle fibers. the circulatory supply of cardiac muscle tissue is more extensive than that of skeletal muscle tissue. cardiac muscle tissue is striated, and composed of sarcomeres.

Explanation:

Cardiac muscle cells are smaller than skeletal muscle fibers. Cardiac muscle cells rely on aerobic respiration for energy as they need to contract continuously. The circulatory supply to cardiac muscle is extensive to meet its high - energy demands. Cardiac muscle is striated and composed of sarcomeres like skeletal muscle.

Answer:

Cardiac muscle cells are much larger than skeletal muscle fibers.
